Question

What is the awnser????

Given: f(x) = 2x + 5 and g(x) = x2 and h(x) = -2x


h(g(f(x))) = ______x² + _____x + ____


1. -8, 4, 8

2. -20, 20, -40

3. 50, -50, 25

Answer 1

-8, -40, -50

Explanation:

if f(x)=2x+5, g(x)=x², h(x)= -2x

h(g(f(x))) = h(g(2x+5)) = h((2x+5)²) = h(4x²+20x+25) = -2(4x²+20x+25)

= -8x²-40x-50
