You can learn about exponential decay here. Keep reading as we not only provide you with the exponential regression formula, but also explain how to calculate exponential regression and explain in what situations the exponential fit proves useful. Both these answers assume the form f(x) = ab^x; however, this presumes that the exponential function has an asymptote at x=0; it also assumes that base is important, but b can always be converted to e. Now you can also solve this problem with the more general f(x) = ae^x + c, which is still exponential, but now leaves the asymptote open to other possibilities and uses the natural base.
