Exponents to Numbers Worksheets

What is Exponential Growth & Decay? When calculating exponential growth and exponential decay, we use the following formula; The general exponential formula is given by; Exponential = y = abx b here is the growth factor, r is the growth or decay rate, and x is the number of time intervals passed. Exponential Growth = y = a (1+r)x. Exponential Decay = y = a(1-r)x. When something is growing continuously, mostly naturally occurring phenomena, we use the term exponential growth to describe it. Bacteria growth or radiation decay are some examples exponentially growing phenomenon. When something is getting reduced continuously, we term it as exponential decay. An example of this is the decreasing air pressure with height.

Bacteria Growth

Did you know that many common bacteria can grow exponentially in a matter of days? The fastest growing bacteria have a reproduction rate of 15 to 20 minutes, when conditions are right.
