Actually, the rate of growth is one of the variables in the exponential-growth equation, which is what you've posted. :oops:

Without further information (such as data points, or the value of y for given values of a and b), I see no way to determine the value of the rate of growth. Sorry.

My only comment- I hope it's helpful- is that decay is negative growth. same formula? negative exponent,
