If so, how? (3.75). For the following exercises, find the x- and y-intercepts for the functions. Best Answer. X intercepts are where the y value is zero. Finding the intercepts of a rational function is similar to finding the intercepts of other normal equations. You can find the x intercept of the equation by setting the value of y to zero and solving the equation.This video shows how to solve x and y intercepts of rational functions.
