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

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

Set up the composite result function.

$f (g (x))$

Evaluate $f (\sqrt{x})$ by substituting in the value of $g$ into $f$ .

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

Multiply $2$ by $\sqrt{x}$ .

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