The weight decreases at a rate of 5 per minute. 065A A e -121 10 -4 t ln065 -121 10 -4 t. Described as a function a quantity undergoing exponential growth is an exponential function of time that is the variable representing time is the exponent in contrast to other.
The two types of exponential functions are exponential growth and exponential decay.
If 0 b 1 the function represents exponential decay. If 0 b 1 the function represents exponential decay. But the unit of the rate is per minute. The weight decreases at a rate of 5 per minute.
