What is Exponential Decay? Where, y is defined as the final amount, a represents the original amount, b is the decay factor and, x represents the amount of passed time. Exponential decay differs from linear decay in terms of decay factor. In the linear function, the original number is decreased by the same amount every time. However, in exponential decay, the decrease in the original amount changes over time. That means the decay factor depends on a certain percentage of the original amount. Let's properly define and understand each of its elements: Decay factor b - Decay factor is defined as the percentage decrease of the original amount.
