A Horizontal Asymptote is an upper bound which you can imagine as a horizontal line that sets a limit for the behavior of the graph of a given function. Both the numerator and denominator are 2 nd degree polynomials. Finding Vertical Asymptotes Of Rational Functions Rational Function Physics And Mathematics Mathematics If the degree of the numerator is less than the degree of the. . Here are the steps to find the horizontal asymptote of any type of function y fx. Horizontal asymptotes occur for functions with polynomial numerators and denominators. Nancy formerly of MathBFF explains the stepsFor how. Enter the function you want to find the asymptotes for into the editor. It is not part of the graph of the function. Let us see some examples to find horizontal asymptotes. Find the horizontal asymptotes for fx x12x. Given fx x12x. If the degree of the numerator of fx is less. In the example a
