1. Problem Description

The problem asks to find the composite function h(g(x))h(g(x)), given g(x)=2x+1g(x) = 2x + 1 and h(x)=3x2h(x) = 3x - 2.

2. Solution Steps

We need to find h(g(x))h(g(x)), which means we need to substitute g(x)g(x) into h(x)h(x).
Given g(x)=2x+1g(x) = 2x + 1 and h(x)=3x2h(x) = 3x - 2.
Substitute g(x)g(x) into h(x)h(x):
h(g(x))=h(2x+1)h(g(x)) = h(2x + 1)
Now, replace xx in the expression for h(x)h(x) with (2x+1)(2x + 1):
h(2x+1)=3(2x+1)2h(2x + 1) = 3(2x + 1) - 2
Expand the expression:
h(2x+1)=6x+32h(2x + 1) = 6x + 3 - 2
Simplify the expression:
h(2x+1)=6x+1h(2x + 1) = 6x + 1

3. Final Answer

h(g(x))=6x+1h(g(x)) = 6x + 1
