Best ResponseYou've already chosen the best response.0just using something a scatter plot in excel, allows you to see that the data forms a parabola. So I'd expect you need to use some software that allows you to do quadratic regression. Its the same as linear regression, but you are using a quadratic equation, rather than a linear equation to describe the data. Most graphics calculations will do quadratic regression. Unfortunately, excel doesn't. hope its of some help.

Best ResponseYou've already chosen the best response.0here is a site that does quadratic regression. http://www.had2know.com/academics/quadraticregressioncalculator.html just enter the 1st value for each point as x and the 2nd value as y. it will give an equation. hope it helps
