$f (x) = - (- 2) + 5$ , $g (x) = 2 (- 2) - 1$

Step 1

Set up the composite result function.

$f (g (x))$

Step 2

Evaluate $f (2 (- 2) - 1)$ by substituting in the value of $g$ into $f$ .

$f (2 (- 2) - 1) = - (- 2) + 5$

Step 3

Multiply $- 1$ by $- 2$ .

$f (2 (- 2) - 1) = 2 + 5$

Step 4

Add $2$ and $5$ .

$f (2 (- 2) - 1) = 7$
