Rewrite the equation in standard form. Determine whether the parabola is horizontal or vertical, the direction it opens, and the vertex.x = y2 + 22y + 124
A. x = (y + 11)2 + 3
horizontal, opens to the right, vertex (3, -11)
B. x = (y + 11)2 + 3
horizontal, opens to the right, vertex (-11, 3)
C. x = (y + 11)2 + 3
horizontal, opens to the left, vertex (3, -11)
D. x = (y - 3)2 - 11
horizontal, opens to the left, vertex (-11, 3)
