Evaluate the Function g(-2)=2x^3+6

$g (- 2) = 2 x^{3} + 6$

Step 1

Replace the variable $x$ with $- 2$ in the expression.

$g (- 2) = 2 {(- 2)}^{3} + 6$

Step 2

Simplify the result.

Simplify each term.

Raise $- 2$ to the power of $3$ .

$g (- 2) = 2 \cdot - 8 + 6$

Multiply $2$ by $- 8$ .

$g (- 2) = - 16 + 6$

Add $- 16$ and $6$ .

$g (- 2) = - 10$

The final answer is $- 10$ .

$- 10$
