$g (x) = 3 x$ $h (x) = x - 4$

Step 1

Set up the composite result function.

$g (h (x))$

Step 2

Evaluate $g (x - 4)$ by substituting in the value of $h$ into $g$ .

$g (x - 4) = 3 (x - 4)$

Step 3

Apply the distributive property.

$g (x - 4) = 3 x + 3 \cdot - 4$

Step 4

Multiply $3$ by $- 4$ .

$g (x - 4) = 3 x - 12$
