Find g(f(x)) f(x)=2x+1 , g(x) = square root of x

$f (x) = 2 x + 1$ , $g (x) = \sqrt{x}$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

Evaluate $g (2 x + 1)$ by substituting in the value of $f$ into $g$ .

$g (2 x + 1) = \sqrt{2 x + 1}$

Step 3

Remove parentheses.

$g (2 x + 1) = \sqrt{2 x + 1}$
