Answer:
A. y = 7(x + 1)²-3
Step-by-step explanation:
Parabola:


Putting into vertex form, remember that:

In this question:
, to put into this format:

We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then
Vertex form:


So the correct answer is:
A. y = 7(x + 1)²-3
