Solution Summary

Asymptotes are found and graphed. The solution is detailed and well presented. The response was given a rating of "5/5" by the student who originally posted the question.

1. How do you determine the vertical asymptotes, given the equation of a rational function? Illustrate with an example. Why can't the graph of that function cross the assymptote? Describe what happens to the graph of a function as the value of the independent variable approaches its vertical asymptote.
2. How do you determin

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=
