Master How to determine the horizontal asymptotes of a rational function

The video tutorial explains how to determine horizontal asymptotes of rational functions. It begins with a brief overview of vertical asymptotes and then delves into the horizontal asymptote test. The test involves comparing the degrees of the numerator and denominator polynomials. If the numerator's degree is greater, there is no horizontal asymptote. If it's less, the asymptote is y=0. If the degrees are equal, the asymptote is y=a/b, where a and b are the leading coefficients. The tutorial includes examples and emphasizes the importance of writing polynomials in descending order.
