8.1.4 Rational Functions (continued) Example 3 Graphing Rational Functions with Vertical Asymptotes
Use the following information to determine the zeros, vertical asymptotes, and horizontal asymptotes of the graph of a rational function. Note that the graphs of some rational functions are not hyperbolas. Also, the graph of a rational function can sometimes cross a horizontal asymptote. However, the graph will approach the asymptote as |x| increases.
