Graph each rational function. ƒ(x)=(20+6x-2x²)/(8+6x-2x²)

Graph each rational function. ƒ(x)=(18+6x-4x²)/(4+6x+2x²)

Provide a short answer to each question. What is the domain of the function $\text{ƒ}\left(x\right)=\frac{1}{x^2}$? What is its range?

Graph each rational function. See Examples 5–9.

$\text{ƒ}\left(x\right)=(16x^2-9)/(x^2-9)$

Provide a short answer to each question. What is the equation of the vertical asymptote of the graph of y=[1/(x-3)]+2? Of the horizontal asymptote?

Work each problem. Which function has a graph that does not have a vertical asymptote?

A. ƒ(x)=1/(x²+2)

B. ƒ(x)=1/(x²-2)

C. ƒ(x)=3/x²

D. ƒ(x)=(2x+1)/(x-8)
