Exponential Growth and Decay
N(t) = No e kt
General form though we could have a number where we have ‘e’.
Here the growth or decay is not linear
ie it does not increase or decrease by the same amount each time.
The growth or decay increases or decreases by multiples of an amount
ie if it doubles each second and you start with 3 units then after 4 seconds, it would be 48 units
The equation for this situation would be
N(t) = 3 (2) t
These questions are not too difficult to solve we just need to be careful. There are several possible questions that can be asked.
