if g(x)=3x+2, find g(-2)

Question

If g(x)=3x+2, find g(-2)

Answer 1

g(-2) means that we evaluate g(x) when x=-2.

 

g(-2) = 3(-2) + 2

g(-2) = -6 + 2

g(-2) = -4

 

 

If we wanted to write this as a coordinate point, it will be  (-2, -4).

Answer 2

Plug in-2 into the right side.

 

 

g(-2) = 3(-2) +2 = -6 +2 = -4

 

g(-2)= -4
