Answer: D
Step-by-step explanation:
Lets go equation by equation.
A) Is an upside down parabola shifted up 2 units. It will have to go downwards so its range is not greater than 2 (it is actually y < 2).
B) This is your regular old parabola, moved up two and shifted right 1. This means that since the graph is shifted up two, it will be y >= 2 (because the lowest point will be at y = 2).
C) This is a line shifted up 8 with a slope of 2. This will definitely go to infinity in both directions so it doesn't have a limited range.
D) This is an exponential graph shifted up two units. It will go beyond y = 2 and up to infinity. So, its range is y >2.
