Find f(g(x)) f(x) = square root of x and g(x)=x+2

$f (x) = \sqrt{x}$ and $g (x) = x + 2$

Step 1

Set up the composite result function.

$f (g (x))$

Step 2

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

$f (x + 2) = \sqrt{x + 2}$

Step 3

Remove parentheses.

$f (x + 2) = \sqrt{x + 2}$
