FitGrowth Command

FitGrowth( <List of Points> ): Calculates a function of the form \( a b ^ x \) to the points in the list. (Very similar to FitExp[ <List of Points> ], just in a slightly different form).

FitGrowth({(0, 1), (2, 3), (4, 3), (6, 4)}) yields 1.31 \( \cdot \) 1.23^x.

You can do a direct least-squares fitting with Fit(list, a*b^x)
