Where and are amounts of some quantity at time and respectively is the decay rate and is the time passed.
Exponential growthdecay formula x t x0 1 r t x t is the value at time t. Exponential growth occurs when the growth rate of the value of a mathematical function is proportional to the functions current value resulting in its growth with time being an exponential function ie a function in which the time value is the exponentExponential decay occurs in the same way when the growth rate is negative. Because this is an exponential decay factor this article focuses on percent decrease. So this is the first case of the type of information we can be given.
