give the intercepts and asymptotes and sketch the graph.

(See attached file for full problem description with proper equations)

Given information in attachment, please sketch the graph.

For the rational function f(x) = (x2 - 1) / (x2 - 9), give the intercepts and asymptotes and sketch the graph.

Let f(x)=0, we get x=1 or x=-1. So, the x-intercepts: x=1 or x=-1.

Let x=0, we get y=1/9. So, the y-intercepts: y=1/9

Vertical asymptotes are x=3 and x=-3 since if x2 - 9=0;

Horizontal asymptotes are y=1, since (x2 - 1) / (x2 - 9) 1 as x goes to infinity
