Exponential Functions An exponential function is in which a constant base is raised to a variable power. Exponential functions are used to model changes in population size‚ in the spread of diseases‚ and the growth of investments. They can also accurately predict types of decline typified by radioactive decay. The essence of exponential growth‚ and a characteristic of all exponential growth functions‚ is that they double in size over regular intervals. The most important exponential function is

moving average and the three period weighted moving average‚ the method that produced the best forecast was the weighted moving average. The reason why the weighted moving average is a better method is essentially because it does not assume that there will be equal weights for each period.
