function f(x) = (x-8)(x+9)

x-intercept means f(x) = 0

(x-8)(x+9) = 0 ⇒ x = 8 or x = - 9

Then there are two points which are x-intercept. They are (8,0) and (-9,-0).

Only (-9,0) is in the list.

The x-intercept of the function is (8, 0) and (-9, 0)

Intercept of a function

Quadratic functions are function with a degree of 2

Given the function as shown;

f(x) = (x-8)(x+9)

The x-intercept is the point where f(x) = 0

Substitute

(x-8)(x+9) = 0
x = 8 and -9

Hence the x-intercept of the function is (8, 0) and (-9, 0)
