Hi Robert,
I don't see an R^2, but are you referring to the X^2?
In the equation, you place your X-Axis distance from the back of the car into X in the equation, and your answer for the Y-Axis offset is given in Y.
Does that answer your question?
As far as fitting a parabola, I'm not quite sure why you would want to simply the equation further, since it is really easy to setup in a spreadsheet and calculate Y for any value of X.
Actually, when it comes time to make a "master template" of this shape for the Insight, I'm going to calculate X-Y moves with the equation and translate that data to a full size template in Styrofoam.
That will allow one to glue blocks and/or sheets of foam to the desired curvature to match the template by AeroHead. This template can be used on all three sides of the car surface, when construction begins.
Jim.
