$f (x) = - 2 x - 7$ , $g (x) = - 4 + 6$ , $((g \circ f)) (- 5)$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

Evaluate $g (- 2 x - 7)$ by substituting in the value of $f$ into $g$ .

$g (- 2 x - 7) = - 4 + 6$

Step 3

Add $- 4$ and $6$ .

$g (- 2 x - 7) = 2$

Step 4

Evaluate the result function by replacing $x$ with $- 5$ in the function.

$2$
