Answer:
D. g(x) = -
-2
Explanation:
The graph appears to have no stretch or shrink so the leading coefficient is either 1 or -1. We can find out that it is -1 because it is a reflection in the x-axis. The change in the y-axis is a shift downwards by -2 so you add that to the end of you equation to get g(x)=-
-2
