$f (x) = 2 x$ $g (x) = x + 5$

Step 1

Set up the composite result function.

$f (g (x))$

Step 2

Evaluate $f (x + 5)$ by substituting in the value of $g$ into $f$ .

$f (x + 5) = 2 (x + 5)$

Step 3

Apply the distributive property.

$f (x + 5) = 2 x + 2 \cdot 5$

Step 4

Multiply $2$ by $5$ .

$f (x + 5) = 2 x + 10$
