Rewrite the equation in standard form. Determine whether the parabola is horizontal or vertical, the direction it opens, and the vertex.y = -5x2 - 120x - 712
A. y = (x - 12)2 + 8
vertical, opens downward, vertex (12, 8)
B. y = (x + 12)2 + 8
vertical, opens downward, vertex (-12, 8)
C. y = (x - 12)2 + 8
vertical, opens upward, vertex (12, 8)
D. y = (x + 12)2 + 8
vertical, opens upward, vertex (-12, 8)
