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

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

Step 1

Replace the variable $x$ with $- 3$ in the expression.

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

Step 2

Simplify the result.

Simplify each term.

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

$f (- 3) = 2 \cdot - 27 + 6$

Multiply $2$ by $- 27$ .

$f (- 3) = - 54 + 6$

Add $- 54$ and $6$ .

$f (- 3) = - 48$

The final answer is $- 48$ .

$- 48$
