I need help creating a math function

[Hell13east]

I am currently creating a spell with triggers, and i would need a trigger / or help.

The spell i am making, is a missile spell, and i would need a function so the missile get's a smooth "ride" (an example: 3x^2 -5x)
however i need this function to work for every value from 200 to 700. is that possible?

Or else, is it possible to create an integer value in a smart way to fix it?

Here's an image of how would like it to be:

If you can help me so it works, you'll recieve + rep

You need a parabola formula?

I made a map with a spell that uses such a function.
Change the parameters to your wishes.

For example:
If you want the missle to describe a larger "circle" (kind of), use

• Set Missle_OffsetTransverse = ((300 x Missle_RealIndex) - (50.00 x (Missle_RealIndex x Missle_RealIndex)))

instead of

• Set Missle_OffsetTransverse = ((200.00 x Missle_RealIndex) - (50.00 x (Missle_RealIndex x Missle_RealIndex)))

etc.
