$f (x) = x + 1$ , $h (x) = x^{2} + 2 x + 1$

Step 1

Set up the composite result function.

$f (h (x))$

Step 2

Evaluate $f (x^{2} + 2 x + 1)$ by substituting in the value of $h$ into $f$ .

$f (x^{2} + 2 x + 1) = (x^{2} + 2 x + 1) + 1$

Step 3

Add $1$ and $1$ .

$f (x^{2} + 2 x + 1) = x^{2} + 2 x + 2$
