Answer:
D. (x+3)^2
Step-by-step explanation:
If we look at basic translation rules we would know that when something moves to the left it becomes a +, we can also see that because the graph moved horizontally the answer must be in a parenthese.
c
b and d both have +3 in the equation, so no.
a only moves the equation down, when we're trying to move it to the left, so C would be the only one left.
