FitExp Command

FitExp( <List of Points> ): Calculates the exponential regression curve in the form aℯ^bx.

FitExp({(0, 1), (2, 3), (4, 3), (6, 4)}) yields 1.31ℯ^0.21x.

If you want the answer in the form \( a b ^ x \) then use the FitGrowth Command.
You can do a direct least-squares fitting with Fit(list, a*exp(b*x))
Euler’s number ℯ can be obtained by pressing ALT + e.
