To get Y=3 ( vertex point), (x+3)^2 must equal 0. And this is possible when X=-3. This condition is only satisfied by Option E

(E). The standard equation of a parabola in vertex form is y = a(x - h) 2 + k, where the vertex is (h, k). Here is the vertex of the parabola described by each answer choice:
(A) (0, 3) On the axis
(B) (3, 3) Incorrect Quadrant
(C) (-3, -3) Incorrect Quadrant
(D) (3, -3) Incorrect Quadrant
(E) (-3, 3) Correct
Only choice (E) places the vertex in the correct quadrant.
