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
