Exponential Growth and Decay Exponential growth is when a growth rate of a mathematical function is proportional to the functions current value. For example the number of microorganisms in a culture will grow exponentially, One breaks into two, two breaks into four, then four into eight and so on. This will continue to grow and flourish untill the nutriets are depleated. Also Economic growth is expressed in percentage terms implying exponential growth, for example U.S GDP per capita has grown at exponetial rate for approximately two percent per year for two centuries.

Somthing is subject to Exponential Decay if it decreases at a rate proportional to its value. There are many examples of Exponential Decay in the real world that are used everyday.Such as vehicles, they are a great example of this because the value of cars will slowly but surely decay over time and the longer you have a vehicle the more the value will decrease.exponential_growth_decay[1].jpg
