Hi all,

I have been algebra free for probably a decade.

Yesterday I thought I wanted to accomplish something easy: finding a function that describes the growth shown in this image:

I did not really get anywhere ... and my colleagues say it is a case for letting a math program determine the function through ... dunno ... something with regression!?

I thought it should not be too hard to calculate the function, but maybe I am wrong!?

What I think I remember tells me that I could write a function that describes how the slope changes ... and then use integral stuff somehow to get the actual function (the antiderivative?).

Or is it possible to use given information from the image to choose values to build an exponential function directly?

Or are my colleagues right? Is it not trivial?
