Find g(3) when g(x)=-2x+3.

g(3) = -3

Step-by-step explanation:

Step 1: Define

g(x) = -2x + 3

g(3) is x = 3

Step 2: Substitute and Evaluate

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

g(3) = -6 + 3

g(3) = -3

g(3) = - 3

Step-by-step explanation:

To evaluate g(3) substitute x = 3 into g(3), that is

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