Math Problem Statement

Evaluate the function h(x) = 4x + 9 at x = 2.

Solution

The problem provided asks you to evaluate the function h(x)=4x+9h(x) = 4x + 9 at x=2x = 2.

To solve this, substitute x=2x = 2 into the function:

h(2)=4(2)+9h(2) = 4(2) + 9

First, calculate the multiplication:

4×2=84 \times 2 = 8

Then, add 9:

8+9=178 + 9 = 17

So, h(2)=17h(2) = 17.
