Question

Four equivalent forms of a quadratic function are given. Which form displays the zeros of function h?

A. h(x) = -4(x − 2)(x + 2)
B. h(x) = -2(2x2 − 8)
C. h(x) = -4(x2 − 4)
D. h(x) = -4x2 + 16

Answer 1

A). because the roots are shown. The roots of this quadratic function would be x=2, and x=-2

Answer 2

A. h(x) = -4(x − 2)(x + 2)

Explanation:

It's easiest to obtain roots from the factorize form

h(x) = -4(x − 2)(x + 2) = 0

x = 2, -2
