Your question does not tell me the formula for the quadratic so I have to make some assumptions.
You say "the graph is reflected over the x axis..." so I presume you mean that x is a quadratic function of y.
The general form of such a quadratic is x = ay^2 + by + c
and the solutions are y = -b +/- sqrt(b^2 - 4ac))/2a
If 4ac > b^2 there are no real roots
If 4ac = b^2 then there is just one root, and the graph just touches the y axis at y = -b/2a
If 4ac < b^2 then there are two roots, and the graph cuts thye y axis at two points given by the +/- term above
