How to Find Horizontal Asymptotes: Rules for Rational Functions

To find horizontal asymptotes for rational functions, compare the degrees of the numerator and denominator. If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y=0. If the degrees are equal, divide the leading coefficients. If the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote.

How to Find Horizontal Asymptotes: Rules for Rational Functions can be determined by examining the degree of the numerator and denominator. Horizontal asymptotes occur when the degrees of the numerator and denominator are equal. If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y = 0. When the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote. Remember to simplify the rational function first by factoring out common factors. Understanding these rules will help you easily identify horizontal asymptotes in rational functions.

Horizontal asymptotes are found by comparing the degrees of the numerator and denominator. For rational functions, if the degree of the numerator is greater, there is no horizontal asymptote. When the degrees are equal, divide the leading coefficients to find the horizontal asymptote. If the degree of the denominator is greater, the horizontal asymptote is y = 0. For rational functions with no horizontal asymptote, there may be a slant asymptote.
  • Use limits to find horizontal asymptotes as x approaches infinity.
  • Horizontal asymptotes help determine the end behavior of rational functions.
  • Vertical asymptotes can affect the existence of horizontal asymptotes.
  • Factor polynomials to simplify rational functions for finding horizontal asymptotes.
  • Graphing rational functions can visually show the horizontal asymptotes.
