$f (x) = 3 x$ , $g (x) = (\frac{x}{3})$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

Evaluate $g (3 x)$ by substituting in the value of $f$ into $g$ .

$g (3 x) = \frac{3 x}{3}$

Step 3

Remove parentheses.

$g (3 x) = \frac{3 x}{3}$

Step 4

Cancel the common factor of $3$ .
