Answer:
D
Explanation:
on a graph if you add numbers to the x variable you move to the right, if you are subtracting from the x variable then you move to the left. If you are adding numbers to the y variable then you are going to be moving up, and if you are subtracting then you are going to be moving down. So 3 units to the left is subtracting 3 from a plot. So that narrows it down to an answer with 2^x-3...
Then we are also given the info that we are going 8 units down, therefor we subtract 8. So the answer should be D. y=(2^x-3)-8
