Evaluate Using the Given Value f(-2)=(-2)^2+4(-2)-5

$f (- 2) = {(- 2)}^{2} + 4 (- 2) - 5$

Step 1

Simplify each term.

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

$f (- 2) = 4 + 4 (- 2) - 5$

Multiply $4$ by $- 2$ .

$f (- 2) = 4 - 8 - 5$

Step 2

Simplify by subtracting numbers.

Subtract $8$ from $4$ .

$f (- 2) = - 4 - 5$

Subtract $5$ from $- 4$ .

$f (- 2) = - 9$
