Lesson Summary:

This lesson on vertical and horizontal asymptotes of rational functions teaches students how to identify vertical asymptotes by setting the denominator equal to zero and solving for x. The lesson also explains how to determine the degrees of the polynomial expressions in the numerator and denominator to locate horizontal asymptotes. If the degrees are equal, the horizontal asymptote is a line crossing the y-axis at a ratio of the leading coefficients. The lesson concludes with a graph illustrating how to plot vertical and horizontal asymptotes and zeros.

Lesson Description:

Locating the vertical and horizontal asymptotes of a rational function. A reminder to set the denominator to zero to locate the vertical asymptotes and to compare the degrees of the expressions in the numerator and denominator to determine if there are horizontal asymptotes and if there are; what they are.
