$f (x) = x^{3} - 1$ , $g (x) = \frac{x - 2}{3}$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

Evaluate $g (x^{3} - 1)$ by substituting in the value of $f$ into $g$ .

$g (x^{3} - 1) = \frac{(x^{3} - 1) - 2}{3}$

Step 3

Subtract $2$ from $- 1$ .

$g (x^{3} - 1) = \frac{x^{3} - 3}{3}$
