Question

Which point is an x-intercept of the quadratic function

f(x) = (x – 8)(x + 9)?

(0,8)
(0,–8)
(9,0)
(–9,0)

Answer 1

C: on edge.

Explanation:

Answer 2

If you would like to find the x-intercept of the quadratic function f(x) = (x - 8) * (x + 9), you can do this using the following steps:

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

(-9, 0): f(-9) = (-9 - 8) * (-9 + 9) = (-17) * 0 = 0
x = -9 and y = 0

The correct result would be (-9, 0).
