Algebra 2 Math Standards

The official Algebra 2 math standards, grouped by domain with the exact code and description for each expectation.

N-CN · The Complex Number System

  • N-CN.1Know there is a complex number \(i\) such that \(i^2 = -1\), and every complex number has the form \(a + bi\) with \(a\) and \(b\) real.
  • N-CN.2Use the relation \(i^2 = -1\) and the commutative, associative, and distributive properties to add, subtract, and multiply complex numbers.
  • N-CN.7Solve quadratic equations with real coefficients that have complex solutions.
  • N-CN.8(+) Extend polynomial identities to the complex numbers. For example, rewrite \(x^2 + 4\) as \((x + 2i)(x - 2i)\).
  • N-CN.9(+) Know the Fundamental Theorem of Algebra; show that it is true for quadratic polynomials.

A-SSE · Seeing Structure in Expressions

  • A-SSE.1.aInterpret parts of an expression, such as terms, factors, and coefficients.
  • A-SSE.1.bInterpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret \(P(1+r)^n\) as the product of \(P\) and a factor not depending on \(P\).
  • A-SSE.2Use the structure of an expression to identify ways to rewrite it. For example, see \(x^4 - y^4\) as \((x^2)^2 - (y^2)^2\), thus recognizing it as a difference of squares that can be factored as \((x^2 - y^2)(x^2 + y^2)\).
  • A-SSE.3.cUse the properties of exponents to transform expressions for exponential functions. For example, the expression \(1.15^t\) can be rewritten as \((1.15^{1/12})^{12t} approx 1.012^{12t}\) to reveal the approximate equivalent monthly interest rate if the annual rate is 15%.
  • A-SSE.4Derive the formula for the sum of a finite geometric series (when the common ratio is not 1), and use the formula to solve problems. For example, calculate mortgage payments.

A-APR · Arithmetic with Polynomials & Rational Expressions

  • A-APR.1Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.
  • A-APR.2Know and apply the Remainder Theorem: For a polynomial \(p(x)\) and a number \(a\), the remainder on division by \(x - a\) is \(p(a)\), so \(p(a) = 0\) if and only if \((x - a)\) is a factor of \(p(x)\).
  • A-APR.3Identify zeros of polynomials when suitable factorizations are available, and use the zeros to construct a rough graph of the function defined by the polynomial.
  • A-APR.4Prove polynomial identities and use them to describe numerical relationships. For example, the polynomial identity \((x^2 + y^2)^2 = (x^2 - y^2)^2 + (2xy)^2\) can be used to generate Pythagorean triples.
  • A-APR.5(+) Know and apply the Binomial Theorem for the expansion of \((x + y)^n\) in powers of \(x\) and \(y\) for a positive integer \(n\), where \(x\) and \(y\) are any numbers, with coefficients determined for example by Pascal's Triangle.
  • A-APR.6Rewrite simple rational expressions in different forms; write \(a(x)/b(x)\) in the form \(q(x) + r(x)/b(x)\), where \(a(x)\), \(b(x)\), \(q(x)\), and \(r(x)\) are polynomials with the degree of \(r(x)\) less than the degree of \(b(x)\), using inspection, long division, or, for the more complicated examples, a computer algebra system.
  • A-APR.7(+) Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.

A-CED · Creating Equations

  • A-CED.1Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.
  • A-CED.2Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
  • A-CED.3Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or non-viable options in a modeling context. For example, represent inequalities describing nutritional and cost constraints on combinations of different foods.
  • A-CED.4Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations. For example, rearrange Ohm's law \(V = IR\) to highlight resistance \(R\).

A-REI · Reasoning with Equations & Inequalities

  • A-REI.1Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.
  • A-REI.11Explain why the \(x\)-coordinates of the points where the graphs of the equations \(y = f(x)\) and \(y = g(x)\) intersect are the solutions of the equation \(f(x) = g(x)\); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where \(f(x)\) and/or \(g(x)\) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.
  • A-REI.2Solve simple rational and radical equations in one variable, and give examples showing how extraneous solutions may arise.
  • A-REI.4.aUse the method of completing the square to transform any quadratic equation in \(x\) into an equation of the form \((x - p)^2 = q\) that has the same solutions. Derive the quadratic formula from this form.
  • A-REI.4.bSolve quadratic equations by inspection (e.g., for \(x^2 = 49\)), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as \(a pm bi\) for real numbers \(a\) and \(b\).
  • A-REI.6Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.
  • A-REI.7Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. For example, find the points of intersection between the line \(y = -3x\) and the circle \(x^2 + y^2 = 3\).

F-IF · Interpreting Functions

  • F-IF.4For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.
  • F-IF.5Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes. For example, if the function \(h(n)\) gives the number of person-hours it takes to assemble \(n\) engines in a factory, then the positive integers would be an appropriate domain for the function.
  • F-IF.6Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph.
  • F-IF.7.bGraph square root, cube root, and piecewise-defined functions, including step functions and absolute value functions.
  • F-IF.7.cGraph polynomial functions, identifying zeros when suitable factorizations are available, and showing end behavior.
  • F-IF.7.eGraph exponential and logarithmic functions, showing intercepts and end behavior, and trigonometric functions, showing period, midline, and amplitude.
  • F-IF.8.bUse the properties of exponents to interpret expressions for exponential functions. For example, identify percent rate of change in functions such as \(y = (1.02)^t\), \(y = (0.97)^t\), \(y = (1.01)^{12t}\), \(y = (1.2)^{t/10}\), and classify them as representing exponential growth or decay.
  • F-IF.9Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a graph of one quadratic function and an algebraic expression for another, say which has the larger maximum.

F-BF · Building Functions

  • F-BF.1.aDetermine an explicit expression, a recursive process, or steps for calculation from a context.
  • F-BF.1.bCombine standard function types using arithmetic operations. For example, build a function that models the temperature of a cooling body by adding a constant function to a decaying exponential, and relate these functions to the model.
  • F-BF.2Write arithmetic and geometric sequences both recursively and with an explicit formula, use them to model situations, and translate between the two forms.
  • F-BF.3Identify the effect on the graph of replacing \(f(x)\) by \(f(x) + k\), \(k,f(x)\), \(f(kx)\), and \(f(x + k)\) for specific values of \(k\) (both positive and negative); find the value of \(k\) given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them.
  • F-BF.4.aSolve an equation of the form \(f(x) = c\) for a simple function \(f\) that has an inverse and write an expression for the inverse. For example, \(f(x) = 2 x^3\) or \(f(x) = (x+1)/(x-1)\) for \(x ne 1\).
  • F-BF.4.b(+) Verify by composition that one function is the inverse of another.
  • F-BF.4.c(+) Read values of an inverse function from a graph or a table, given that the function has an inverse.
  • F-BF.4.d(+) Produce an invertible function from a non-invertible function by restricting the domain.
  • F-BF.5(+) Understand the inverse relationship between exponents and logarithms and use this relationship to solve problems involving logarithms and exponents.

F-LE · Linear, Quadratic & Exponential Models

  • F-LE.4For exponential models, express as a logarithm the solution to \(a,b^{ct} = d\) where \(a\), \(c\), and \(d\) are numbers and the base \(b\) is 2, 10, or \(e\); evaluate the logarithm using technology.

S-ID · Interpreting Data

  • S-ID.4Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve.

S-CP · Conditional Probability & the Rules of Probability

  • S-CP.1Describe events as subsets of a sample space (the set of outcomes) using characteristics (or categories) of the outcomes, or as unions, intersections, or complements of other events (``or,'' ``and,'' ``not'').
  • S-CP.2Understand that two events \(A\) and \(B\) are independent if the probability of \(A\) and \(B\) occurring together is the product of their probabilities, and use this characterization to determine if they are independent.
  • S-CP.3Understand the conditional probability of \(A\) given \(B\) as \(P(A text{ and } B)/P(B)\), and interpret independence of \(A\) and \(B\) as saying that the conditional probability of \(A\) given \(B\) is the same as the probability of \(A\), and the conditional probability of \(B\) given \(A\) is the same as the probability of \(B\).
  • S-CP.4Construct and interpret two-way frequency tables of data when two categories are associated with each object being classified. Use the two-way table as a sample space to decide if events are independent and to approximate conditional probabilities.
  • S-CP.5Recognize and explain the concepts of conditional probability and independence in everyday language and everyday situations. For example, compare the chance of having lung cancer if you are a smoker with the chance of being a smoker if you have lung cancer.
  • S-CP.6Find the conditional probability of \(A\) given \(B\) as the fraction of \(B\)'s outcomes that also belong to \(A\), and interpret the answer in terms of the model.
  • S-CP.7Apply the Addition Rule, \(P(A text{ or } B) = P(A) + P(B) - P(A text{ and } B)\), and interpret the answer in terms of the model.

S-IC · Making Inferences

  • S-IC.1Understand statistics as a process for making inferences about population parameters based on a random sample from that population.
  • S-IC.2Decide if a specified model is consistent with results from a given data-generating process, e.g., using simulation. For example, a model says a spinning coin falls heads up with probability 0.5. Would a result of 5 tails in a row cause you to question the model?
  • S-IC.3Recognize the purposes of and differences among sample surveys, experiments, and observational studies; explain how randomization relates to each.
  • S-IC.4Use data from a sample survey to estimate a population mean or proportion; develop a margin of error through the use of simulation models for random sampling.
  • S-IC.5Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant.
  • S-IC.6Evaluate reports based on data.

F-TF

  • F-TF.1Understand radian measure of an angle as the length of the arc on the unit circle subtended by the angle.
  • F-TF.2Explain how the unit circle in the coordinate plane enables the extension of trigonometric functions to all real numbers, interpreted as radian measures of angles traversed counterclockwise around the unit circle.
  • F-TF.5Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline.
  • F-TF.8Prove the Pythagorean identity \(sin^2(theta) + cos^2(theta) = 1\) and use it to find \(sin(theta)\), \(cos(theta)\), or \(tan(theta)\) given \(sin(theta)\), \(cos(theta)\), or \(tan(theta)\) and the quadrant of the angle.
  • F-TF.9(+) Prove the addition and subtraction formulas for sine, cosine, and tangent and use them to solve problems.
