How to find the x and y intercepts of a rational function

The x-intercept(s) of a function occurs when y = 0 and the y-intercept(s) of a function o 👉 Learn how to find the x and y-intercepts of a rational function.

Finding Intercepts of Rational Fractions

We can get the x x x intercepts by setting y = 0: (x − 1) (x − 2) (x − 3) x (x − 1) (x + 1) = 0 y=0: \dfrac{(x-1)(x-2)(x-3)}{x(x-1)(x+1)} = 0 y = 0: x (x − 1) (x + 1) (x − 1) (x − 2) (x − 3) = 0.

How to find the x and y-intercepts of a rational function?

The x-intercept (s) of a function occurs when y = 0 and the y-intercept (s) of a function occurs when x = 0. To find the y-intercept of a function, we plug in zero for x and solve
