Learn how to graph a rational function when the function intercepts horizontal asymptote

The video tutorial explains how to graph rational functions by identifying vertical and horizontal asymptotes. It begins with finding vertical asymptotes by setting the denominator to zero and solving for x. The tutorial then covers horizontal asymptotes by comparing the degrees of the numerator and denominator. Finally, it demonstrates graphing the function using a graphing calculator and evaluating points around the asymptotes.
