Determining exponential growth or decay
WebOct 13, 2024 · Exponential decay is the change that occurs when an original amount is reduced by a consistent rate over a period of time. Here's an exponential decay function: y = a ( 1 -b)x y: Final amount remaining after the decay over a period of time a: The original amount x: Time The decay factor is (1- b) WebIntroduce your students to the concept of exponential growth and decay in a real-world context with this interactive project!
