Find g(f(x)) f(x) = square root of x-3 , g(x)=4x

$f (x) = \sqrt{x - 3}$ , $g (x) = 4 x$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

Evaluate $g (\sqrt{x - 3})$ by substituting in the value of $f$ into $g$ .

$g (\sqrt{x - 3}) = 4 (\sqrt{x - 3})$

Step 3

Multiply $4$ by $\sqrt{x - 3}$ .

$g (\sqrt{x - 3}) = 4 \sqrt{x - 3}$
