Asymptotes of Rational Functions

How Do You Graph a Rational Function by Finding its Asymptotes and Zeros?

In a rational function, the denominator of the rational expression holds the key to the location of the vertical asymptotes. The relationship between degrees of the numerator and denominator determine the nature of the horizontal asymptotes. Check out the tutorial to learn more!
