C= 0
D= 5g
Step-by-step explanation:
I think this is right. I'm not sure what g(x) = 2-5x is for but these are the answers if you evaluate a b c and d.n
Answer: Work below
Step-by-step explanation:
g(-1) = 2 - 5x (Plug in -1 for x)
= 2 - 5(-1) = 2 - ( - 5 ) = 2 + 5 = 7
A): 7
g(-2) = 2 - 5x
= 2 - 5(-2) = 2 - ( - 10 ) = 2 + 10 = 12
B): 12
g(0) = 2 - 5x
= 2 - 5(0) = 2 - 0 = 2
C): 2
g(5) = 2 - 5x
= 2 - 5 ( 5 ) = 2 - 25 = -23
D): -23
