Answer:
D
Step-by-step explanation:
Answers A and B are dead wrong so you need to consider only answers C or D.
The difference in answers C or D is only the factor (x -2) or (x + 2).
Please remember this (and never forget it):
if you shift a function to the right, it means the sign is Negative.
if you shift a function to the left, it means the sign is PLUS.
It is a bit counterintuitive, but true none the less!
So now you know it is answer D (where as you might initially think it should be C).
