The presenter explains that exponential decay occurs when the growth rate is negative and provides examples of how to calculate the values of a and b in the exponential decay equation. The video also explains the general exponential formula and how to find the Y intercept and rate of growth. The presenter covers the topic of negative powers and demonstrates how to solve exponential decay problems. The lesson ends with a sample problem involving a radioactive substance with a half-life of 20 days.\n
