Answer:
39
Step-by-step explanation:
g(x) = 3x-2,
First find g(8)
g(8) = 3(8) -2 = 24-2 =22
The find g(-5) = 3(-5) -2 = -15-2 =-17
The subtract g(-5) from g(8)
g(8) -g(-5) = 22 - -17 = 22+17=39
Find g(8)
Substitute 8 in for x
g(x)=3x-2
g(8)=3(8)-2
=24-2
=22
Find g(-5)
Substitute -5 in for x
g(-5)=3(-5)-2
= -15-2
= -17
Now, subtract
g(8) - g (-5)
22- -17
22+17
