Exponential growth is a pattern of data that shows greater increases with passing time, creating the curve of an exponential function.

You could use a computer to fit an exponential function to the data and measure how well it fits. But how about just turning an exponential function into a linear function?

Experimental research in the field has shown that the decomposition and accumulation processes of litter do not follow a course that could be represented by an exponential function. Possibly an ...
