$f (x) = x - 2$ , $g (x) = x^{2} + 3 x + 4$

Step 1

Set up the composite result function.

$f (g (x))$

Step 2

Evaluate $f (x^{2} + 3 x + 4)$ by substituting in the value of $g$ into $f$ .

$f (x^{2} + 3 x + 4) = (x^{2} + 3 x + 4) - 2$

Step 3

Subtract $2$ from $4$ .

$f (x^{2} + 3 x + 4) = x^{2} + 3 x + 2$
