I am looking for a something like the Excel FORECAST
function, except it should work for a quadratic equation
instead of linear equation. I already understand how to
use the Excel quadratic line fitting formula to get the
coefficients (a,b,c) in y = ax^2+bx+c. What I want to
know is how to predict a value for the next interval (next
x-value) based on the formula without having to fill in
the x-value into the equation.
