Consider the graph of the equation y=ax^2+bx+c, when a does not equal 0. If a is multiplied by 3, what is true of the graph of the resulting parabola?
(A) The Vertex is 3 units above the vertex of the original.
(B) The new parabola is wider than the original.
(C) The new parabola is 3 units to the right of the original.
(D) The new parabolais narrowerthan the original.
