Answer:
f(8) = -161
Step-by-step explanation:
Plugin 8 to each x value to get to this equation, -3(8)^2 + 3(8) + 7. Once you have done that, make sure to multiply 8 to the second power and by 3 separately to get to this equation -3(64) + 24 + 7. Combine 24 and 7 together to get 31 and multiply 64 by -3 to get -192. Add 31 now to get -161 as your answer.
Answer:
f(8)= -161
Step-by-step explanation:
fill in 8 into x, so the equation becomes
f(8)=-3(8)^2+3(8)+7
f(8)=-3(64)+24+7
f(8)=-192+31
f(8)=-161
