Find g(f(x)) f(x)=7x+4 , g(x) = square root of x

$f (x) = 7 x + 4$ , $g (x) = \sqrt{x}$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

Evaluate $g (7 x + 4)$ by substituting in the value of $f$ into $g$ .

$g (7 x + 4) = \sqrt{7 x + 4}$

Step 3

Remove parentheses.

$g (7 x + 4) = \sqrt{7 x + 4}$
