Evaluate the Function f(-4)=2x^3+2

$f (- 4) = 2 x^{3} + 2$

Step 1

Replace the variable $x$ with $- 4$ in the expression.

$f (- 4) = 2 {(- 4)}^{3} + 2$

Step 2

Simplify the result.

Simplify each term.

Raise $- 4$ to the power of $3$ .

$f (- 4) = 2 \cdot - 64 + 2$

Multiply $2$ by $- 64$ .

$f (- 4) = - 128 + 2$

Add $- 128$ and $2$ .

$f (- 4) = - 126$

The final answer is $- 126$ .

$- 126$
