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

A. h(x) = -4(x − 2)(x + 2)

Step-by-step explanation:

It's easiest to obtain roots from the factorize form

h(x) = -4(x − 2)(x + 2) = 0

x = 2, -2

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
