Question

I need the answer and show work for this question

Answer 1

f(3) =-12

f(-1) =-12

Explanation:

HELLO THERE

f(3)=-2(3)^2+8(3)

f(3)=-36+24

f(3)=-12

----------------------------

f(-1) =2(-1) ^2+8(-1)

f(-1) =-4-8

f(-1) =-12

//Both equal -12//

HAVE A GREAT DAY

Answer 2

Explanation:

f(x) = -2x² + 8x

f(3) = -2*(3)² + 8*3

= - 2*9 + 24

= - 18+ 24

f(3) = 6

f(1)= -2*(-1)² + 8*(-1)

= -2*1 - 8

= - 2 -8

f(1) = -10
