How to Graph Rational Expressions? (+FREE Worksheet!)
Graphing Rational Expressions – Example 2: Graph rational expressions. \(f(x)=\frac{3x}{x^2-2x}\) Solution: First, notice that the graph is in two pieces. Find \(y\)-intercept by substituting zero for \(x\) and solving for \(y (f(x)): x=0→y=\frac{3x}{x^2-2x}=\frac{3(0)}{(0^2-2(0)}=\frac{0}{0}\), \(y\)-intercept: None Asymptotes of \(\frac{3x}{x^2-2x}\): vertical: \(x=2\), Horizontal: \(y=0\) After finding the asymptotes, you can plug in some values for \(x\) and […]
