I believe that the answer is C, I don't know if it is addition or multiplication, but if is is addition, it would be 146, C
You can multiply it out to get
... 3x² - 9x + 6
and you can write it in vertex form as
... 3(x -3/2)² -3/4

Answer:
Step-by-step explanation:
Putting value of n = - 8 in the equation
F(n) = 2n− 5
F(-8) = 2(-8) - 5
= - 16 - 5 = - 21
