The functions f and g are defined as follows. f(x) = 2x^3+ 2 g(x) = 2x-3

Find f(-4) and g(-7).

Simplify your answers as much as possible.

1. F(-4)= 2(-4^3) + 2
F(-4)= 2(-64) +2
F(-4)= -128 +2
So F(-4)= -126 is your answer
2. G(-7)= 2(-7)-3
G(-7) = -14 -3
So G(-7)= -17

Hope this helps

Dm me pls mike and
