Formulas

x-intercept: Set the numerator of the function equal to zero and solve for x.
y-intercept: Substitute x = 0 into the function.

Theorems

A rational function's x-intercepts occur where the numerator is zero, provided the denominator is not zero.
A rational function's y-intercept occurs where x = 0, provided the function is defined at x = 0.
