math equations to map out an objects path

[fattymc03]

lets say i want to have an object come on screen and follow a certain path. like if i wanted it to follow y=x^2 where x > 0, so the object travels along a curve (right half of parabola). if i actually moved it along those returned x,y values the animation would of course become jumpy since x is increasing exponentially. what should i do to just make it follow the path without actually using the math. sorry if this doesnt make sense. i cant type it the way im thinking about it

I think I know what you meant. Use y as a domain instead of x, i.e. x = sqrt(y), y > 0.

Hope it helps.
