Math Problem Statement

solve

Given h(x) = 4x - 2, find h(x + 2).

Solution

To solve the problem, we are given the function h(x)=4x2h(x) = 4x - 2, and we need to find h(x+2)h(x + 2).

Step 1: Substitute x+2x + 2 into the function

We replace xx with x+2x + 2 in the expression for h(x)h(x): h(x+2)=4(x+2)2h(x + 2) = 4(x + 2) - 2

Step 2: Simplify the expression

Expand the brackets: h(x+2)=4x+82h(x + 2) = 4x + 8 - 2 Combine like terms: h(x+2)=4x+6h(x + 2) = 4x + 6

Final Answer:

h(x+2)=4x+6h(x + 2) = 4x + 6
