Find the Horizontal and Vertical Asymptotes of a rational function

The video tutorial explains how to find the domain and asymptotes of a rational function. It begins by identifying the domain by setting the denominator to zero. The tutorial then covers horizontal asymptotes by comparing exponents of the polynomials and determining the asymptote based on their relationship. Vertical asymptotes are found by setting the numerator to zero. The lesson concludes with a brief interruption.

Explain how to find the domain of the function given that the denominator is set to zero.

What happens to the horizontal asymptote when the degree of the numerator is greater than that of the denominator?
