Step-by-step explanation:

g(x) is equal to 3x - 2, when a number is replaced in "g(x)", this will also replace the x in the equation that g(x) represents.

We have g(8) - g(-5), meaning that we will grab 3x - 2 and replace it with both 8 and -5. Then subtracting both equations.

g(8) = 3(8) - 2

g(8) = 24 - 2

g(8) = 22

g(-5) = 3(-5) - 2

g(-5) = -15 - 2

g(-5) = -17

Now go back to the original equation of g(8) - g(-5) and get our answers to replace both.

22 - (-17)

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
