Sagot :
Answer:
A
Step-by-step explanation:
Easy method for this question is to plug the point (-1,7)
Plug -1 as x and hope we can get 7
[tex]y =-2(-1+1)^{2}+7\\y=7\\[/tex]
so your answer is going to be A
explanation : your vertex is the 2 last numbers, and the reason the 1 is negative is because the h always flips
so if it was positive, it would flip to a negative number instead
