The specified coordinates to the moving images, similar products into the effect of buying car?

This is a math problem, goods into buying a car, shopping cart and button,
Assuming that coordinates (0, 0) button, shopping cart coordinates (c, d) both the path of the constitute a parabolic shape
C, d for known number
Countable equation y=ax ^ 2 + bx, through (0, 0),
At the same time in order to satisfy the parabolic fall within (c, d), so the d=ac ^ 2 + BC
B=(d - ac ^ 2)/c
Get the equation y=ax ^ 2 + (d - ac ^ 2) x/c
Need appeared in the process of flying parabola vertex animation, so the points need to be on the right side of the vertex b/2 c, so c> B/2
So the equation a need to meet a> D/c ^ 2-2

Y=ax ^ 2 + (d - ac ^ 2) x/c
A> D/c ^ 2-2

Have a code? Thank you very much!

Ensure give you the code or not.
