Evaluate the Function f(-2)=3x^3+5

$f (- 2) = 3 x^{3} + 5$

Step 1

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

$f (- 2) = 3 {(- 2)}^{3} + 5$

Step 2

Simplify the result.

Simplify each term.

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

$f (- 2) = 3 \cdot - 8 + 5$

Multiply $3$ by $- 8$ .

$f (- 2) = - 24 + 5$

Add $- 24$ and $5$ .

$f (- 2) = - 19$

The final answer is $- 19$ .

$- 19$
