Question

If g(x) = 3x-2, find g(8) -g(-5)

Answer 1

39

Explanation:

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(x)=3x-2

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

= -15-2

= -17

Now, subtract

g(8) - g (-5)

22- -17

22+17

39

Answer 2

39

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
