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.

Exponential growth is a process that increases quantity over time. Linear functions change at a constant time per unit interval. Exponential functions can also be used to model populations that shrink from deadly diseases or maybe chemical compounds that break down over time. These models exhibit exponential decay and not exponential growth. Exponential growth and decay worksheets help students build a base in understanding the exponential growth and decay over time using related word problems. Exponential growth always shows a sharper increase over time. Examples of exponential growth include spoilage of food, human population, microorganism in culture, etc.

In this video, you will learn how to use a table and a formula to find the percentage of a radioactive substance that remains after a certain time. You will also see how a common ratio, which is the factor by which the quantity changes every time period, determines the rate of change.
