Question

Evaluate the function when x=−2, 0, and 5.

g(x)=3x−2


g(−2)=

g(0)=

g(5)=


I'm very confused, please help!

Answer 1

Explanation:

g(x)=3x−2

g(−2)= 3(-2) - 2 (after substituting -2 for x): g(-2) = -6 - 2 = -8

g(0)= 3(0) - 2 = -2

g(5)= 3(5) - 2 = 13

Answer 2

g(x) = 3x-2
g(-2) = 3(-2) - 2
g(-2) = -6-2
g(-2) = -8

g(0) = 3(0)-2
g(0) = 0-2
g(0) = -2

g(5) = 3(5)-2
g(5) = 15-2
g(5) = 13
