Which of the following is an x-intercept of the function, f(x) = x^2 - 64 ?
1 answer:
Answer:
D. -8
Step-by-step explanation:
An x intercept is where the y value is zero.
We set the expression equal to zero and solve for x.
x^2 - 64 = 0
(x + 8)(x - 8) = 0
x + 8 = 0 or x - 8 = 0
x = 8 or x = 8
Answer: D. -8
