$f (x) = - x^{3} - x^{2} + 20 x$ , $g (x) = 0$

Step 1

Set up the composite result function.

$f (g (x))$

Step 2

Evaluate $f (0)$ by substituting in the value of $g$ into $f$ .

$f (0) = - {(0)}^{3} - {(0)}^{2} + 20 (0)$

Step 3

Simplify each term.

Step 3.1

Raising $0$ to any positive power yields $0$ .

$f (0) = - 0 - {(0)}^{2} + 20 (0)$

Step 3.2

Multiply $- 1$ by $0$ .

$f (0) = 0 - {(0)}^{2} + 20 (0)$

Step 3.3

Raising $0$ to any positive power yields $0$ .

$f (0) = 0 - 0 + 20 (0)$

Step 3.4

Multiply $- 1$ by $0$ .

$f (0) = 0 + 0 + 20 (0)$

Step 3.5

Multiply $20$ by $0$ .

$f (0) = 0 + 0 + 0$

Step 4
