F(x) = x^2 + 3x + 2
if g(x) is the reflection of f(x) across the x - axis then
g(x) = -f(x)
g(x) = - (x^2 + 3x + 2)
g(x) = - x^2 - 3x - 2

Please help! functions operations. explain please
ValentinkaMS [17]

Answer:

a. 40

Step-by-step explanation:

Given

g(x)=2x and h(x)=x^2+4

(h\circ g)(x)=h(g(x))

(h\circ g)(x)=h(2x)

We plug in 2x into  h(x)=x^2+4.

(h\circ g)(x)=(2x)^2+4

(h\circ g)(x)=4x^2+4

We now substitute x=-3.

(h\circ g)(-3)=4(-3)^2+4

(h\circ g)(-3)=36+4=40

The correct choice is A.
