WebSep 22, 2024 · A Power Law of the first order, also called linear function: f (x) = ax 1. If the exponent of an exponential function equals 2 - in fact, if it’s higher than 1 - we have a “real” Power Law. A Power Law of the second order: f (x) = ax 2. If the exponent is 3, the power law is scaled to the 3rd power.
