Evaluate Using the Given Value f(-2)=3(-2)^2-3*-2

$f (- 2) = 3 {(- 2)}^{2} - 3 \cdot - 2$

Step 1

Simplify each term.

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

$f (- 2) = 3 \cdot 4 - 3 \cdot - 2$

Multiply $3$ by $4$ .

$f (- 2) = 12 - 3 \cdot - 2$

Multiply $- 3$ by $- 2$ .

$f (- 2) = 12 + 6$

Step 2

Add $12$ and $6$ .

$f (- 2) = 18$
