The vertex of this parabola is at (-3,2) which of the following could be its equation a. y=4(x-3)^2+2 b. y=4(x+3)^2-2 c. y=4(x-3)^2-2 d. y=4(x+3)^2+2

D

Step-by-step explanation:

Vertex form is y=a(x-h)^2+k where (h,k) is vertex

So replace h with -3 and k with 2  

y=a(x--3)^2+2

y=a(x+3)^2+2

So the only choice it could be is D
