are there any statisticians or mathematicians here? I am trying to remember the meaning of exponential growth. I have googled it and yes, there is of course an equation. I was mixing it with logarithmic growth..   I was thinking if it is a constant rate, like it goes up 4% a day, that would be a linear growth. Even if it is by 50% a day. If it went up 4% one day, 16% next, squared or by a constant rate of increase..that would be exponential. I know it does not mean lots and lots and lots of growth in vague terms and no mathematics..i took graduate statistics years, nay decades ago..so I would like to see this discussed by people who know..
