Exponential growth and decay of bacterial colonies

Exponential growth is a specific way that a quantity may increase over time. It occurs when the instantaneous rate of change of a quantity with respect to time is proportional to the quantity itself. f(x)a(1+r)x f(x) exponential growth function a initial amount r growth rate x number of time intervals , exponentialGrowthFunction, growthRate, Genetics, Microbiology, decay
