WebNov 16, 2024 · Process for Graphing a Rational Function Find the intercepts, if there are any. Remember that the y y -intercept is given by (0,f (0)) ( 0, f ( 0)) and we find the x x -intercepts by setting the numerator equal to zero … WebWhen finding asymptotes always write the rational function in lowest terms. It is best not to have the function in factored form Vertical Asymptotes Set the denominator equation to zero and solve for x. The equation for a vertical asymptote is written x=k, where k is the solution from setting the denominator to zero. *If you substitute k into ...
