Exponential functions are functions that model a very rapid growth or a very rapid decay of something. The AIC for this one parameter model is worse than for the 3 parameter model (compare AIC(fm1) and AIC(fm3)) but the one parameter model might still be preferable due to its parsimony and the fact that the fit is visually indistinguishable from the 3 parameter model. The inverse of the exponential function is the natural logarithm which represents the opposite of exponential growth,exponential decay.
