Exponential decay is the change that occurs when an original amount is reduced by a consistent rate over a period of time. Exponential growth and decay can be determined with the following equation. T is the time in discrete intervals and selected time units.
Y a 1b x.
The exponential growth formula can be mentioned as- Exponential Growth y a 1 r x. In this equation N refers to the final population NI is the starting population t is the time over which the growth or decay took place and the k represents the growth or decay constant. To find the value of the account at ten years t10. Using Exponential Functions to Model Growth and Decay In exponential growth the value of the dependent variable y increases at a constant percentage rate as the value of the independent variable x or t increases.
