In the xy-plane, a parabola has vertex (9, -14) and intersects the z-axis at two points. If the equation of the parabola is written in the form y = ar² + bx + c , where a, b, and c are constants, which of the following could be the value of a, b, c ?
a) a = -1, b = -18, c = 245
b) a = 1, b = -18, c = 245
c) a = -1, b = 18, c = -245
d) a = 1, b = 18, c = -245
