Answer:
D
Explanation:
Think about some easy coordinates. If you plug in x=0, the y coordinate must be 2, eliminating B.
Next, as x becomes larger and larger, the y value decreases. This means that the value inside the bracket must be less than 1. If it is greater than 1, the y value would increase as x increased.
To illustrate, 2 < 2^2 < 2^3 < 2^4
However, 0.5 > 0.5^2 > 0.5^3
You can check this in your calculator if you need to.
