  # How to find x intercept of rational function

To find the x-intercept of a rational function, set y=0 and solve for x. For example, consider the rational function f(x)=2x/(x^2+1). To find the x-intercept, set y=0 and solve for x:  ## How to Find x and y Axis Intercepts

To find the x-intercept, we must substitute in 0 for y or f (x): And then solve by cross-multiplying: 0 = x + 10 x = -10 There is a y-intercept at . (Notice that 0 is the y coordinate because on the x

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

For this rational function, f ( x) = x 2 − 3 x x 2 + 2 x − 48 = x · ( x − 3) ( x + 8) · ( x − 6) . Since there are no common factors between the numerator and the denominator, the
