$f (x) = x^{3}$ , $g (x) = \sqrt[3]{x}$

Step 1

Set up the composite result function.

$g (f (x))$

Step 2

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

$g (x^{3}) = \sqrt[3]{x^{3}}$

Step 3

Remove parentheses.

$g (x^{3}) = \sqrt[3]{x^{3}}$

Step 4

Pull terms out from under the radical, assuming real numbers.

$g (x^{3}) = x$
