a, b and c are constants defined to fit the curve..
Also, as you notice, the Y value decreases with each X, but it will gradually converge and not decrease after a certain value of X.
So, I want to extrapolate the curve such that, at very high value of X (X = infinity), function Y converges to its asymptotic value..
In other words, with a certain high number of 'X', the "a*exp[-X/b]" term will tend toward 0, where "c" represents the convergence, and that value of "c" is being taken as final result..
Any type of help is appreciated.. Thanks for your consideration
