Find g(f(x)) f(x)=9x+7 , g(x) = square root of x

$f (x) = 9 x + 7$ , $g (x) = \sqrt{x}$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

Evaluate $g (9 x + 7)$ by substituting in the value of $f$ into $g$ .

$g (9 x + 7) = \sqrt{9 x + 7}$

Step 3

Remove parentheses.

$g (9 x + 7) = \sqrt{9 x + 7}$
