Exponential function/Talk

Aren't there multiple forms of the exponential function? Specifically, isn't the most general form ka^bx ? Admittedly, the differences can be incorporated in to b thus: ke^bxln(a), but wouldn't the first form be more clear to the laymen?

You don't really need the b; the most general form is ka^x. I mention these in the "science" paragraph; they are indeed the most useful to the "laymen". However they cannot be defined without exp(x) and in mathematics, exp(x) is tremendously more important than a^x, so I started the article with exp(x) and then came to a^x as soon as possible. --AxelBoldt
