Inverse function of a negative parabola?

Depending on the domain and range, the inverse may or may not be defined. Assuming it is defined, the inverse function can be derived as follows: The negative parabola is y = -ax2 + bx + c (where a>0) so that -ax2 + bx + c - y = 0 using the quadratic formula, x = [-b ± sqrt(b2 + 4*a*(c-y)]/(-2a) which is a square root function, and will be real provided that b2 + 4*a*(c-y) > 0
