comment Find quadratic equation based on 2 tangents
In comments below you say you are looking for a parabola, and not just any quadratic equation. Do you have any limitations or preferences on the kind of a parabola, for example if its axis should be parallel to the X or Y axis?

comment One to one and onto
Neither of those are functions by the regular definition. The first one defines several mappings for one value, and the second doesn't define a mapping for 3.
