Neatly showing why when all you have is two data points you can’t just assume the best fit function for extrapolation is a linear one.

Mind you, a surprisingly large number of political comments is anchored in exactly that logic.

Doubling every three months is an exponential Interpolation and not a linear one!

Good point and well spotted!

By tweaking a few parameters you can turn every base into any other base for exponentials. Just use e^(ln(b)*x)

By that definition you can turn any linear function a * x + b, “exponential” by making it e ^ln(a*x +b).

It doesn’t matter if you divide ln(2) or x by three, it’s the same thing.
