Graph a rational function and determine the horizontal and vertical asymptotes

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. Then, it covers horizontal asymptotes by comparing the degrees of the numerator and denominator and using leading coefficients. The tutorial concludes with graphing the function using points around the asymptotes and emphasizes the importance of understanding the process manually, even when graphing technology is available.
