$h (x) = \sqrt{x - 4} + 4$ , $f (x) = \sqrt{x}$

Step 1

Set up the composite result function.

$f (h (x))$

Step 2

Evaluate $f (\sqrt{x - 4} + 4)$ by substituting in the value of $h$ into $f$ .

$f (\sqrt{x - 4} + 4) = \sqrt{\sqrt{x - 4} + 4}$

Step 3

Remove parentheses.

$f (\sqrt{x - 4} + 4) = \sqrt{\sqrt{x - 4} + 4}$
