## How to Graph Rational Expressions

In this post, you will learn how to graph Rational Expressions. You can graph Rational Expressions in a few simple steps. A step-by-step guide to Graphing Rational Expressions A rational expression is a fraction in which the numerator and/or the denominator are polynomials. Examples: $$\frac{1}{x},\frac{x^2}{x-1},\frac{x^2-x+2}{x^2+5x+1},\frac{m^2+6m-5}{m-2m}$$To graph a rational function: Find the vertical asymptotes of the function if there are any. (Vertical asymptotes are vertical lines that correspond to the zeroes of the denominator. The graph will have a vertical asymptote at...
