Determining the asymptotes of a rational function

The video tutorial explains how to find vertical and horizontal asymptotes in rational functions. It begins with setting the denominator to zero to find vertical asymptotes and discusses how this relates to the domain. The tutorial then covers rules for horizontal asymptotes based on the degrees of polynomials, explaining when the asymptote is zero, a fraction, or nonexistent. The video concludes with a brief mention of slant asymptotes, which will be covered in future lessons.
