Answer:

B)
f(x)=-3(x+1)^2+2

Explanation:

Notice that the graph of the parabola opens downward. This tells us that the leading coefficient of the function must be negative. Hence, we can rule out answers A and D.

Also, notice that our vertex is
(h,k)\rightarrow(-1,2), which when we plug into vertex form, we get
y=a(x-h)^2+k\rightarrow y=a(x-(-1))^2+2\rightarrow y=a(x+1)^2+2.

This means that B is the correct function that represents the graph.
