Question

Find g(-2) + h(4) if g(x)= 5-2x and h(x) = - x2 pls help

Answer 1

-7

Explanation:

Substitute -2 into g(x) equation,

g(x) = 5 - 2x

g(-2) = [5 - 2(-2)] = 9

Substitute 4 into h(x) equation,

h(x) = -x^2

h(4) = [-(4)^2] = -16

Therefore,

g(-2) + h(4) = 9 + (-16) = -7

Answer 2

-7

Explanation:

g(x)= 5-2x and h(x) = - x^2

g(-2) + h(4)

First find g(-2)

g(-2) = 5 -2(-2) = 5 +4 = 9

Then find h(4) = - 4^2 = -16

g(-2) + h(4) = 9-16 = -7
