Answer:
Kindly check explanation
Step-by-step explanation:
When we have an exponential function, this means that a certain item of sum changes by a fixed percentage rate over a certain period of time.
Decay in Mathematics means reduction. Hence, Applying this knowledge to the concept of exponential Decay, we could say exponential deacy means a reduction process an object or thin undergoes as it decreases by a fixed percentage rate over a certain period of time.
Mathematically, exponential Decay is expressed as :
y = a(1-b)^x
Where, a = Initial amount
(1 - b) = Decay factor ; where b = decay rate.
x = period.
