Evaluate Using the Given Value f(7)=-16(7)^2+34(7)+80

$f (7) = - 16 {(7)}^{2} + 34 (7) + 80$

Step 1

Simplify each term.

Raise $7$ to the power of $2$ .

$f (7) = - 16 \cdot 49 + 34 (7) + 80$

Multiply $- 16$ by $49$ .

$f (7) = - 784 + 34 (7) + 80$

Multiply $34$ by $7$ .

$f (7) = - 784 + 238 + 80$

Step 2

Simplify by adding numbers.

Add $- 784$ and $238$ .

$f (7) = - 546 + 80$

Add $- 546$ and $80$ .

$f (7) = - 466$
