Understanding Exponential Decay

The video tutorial explains the concept of half-life using cesium-137 as an example. It covers exponential decay functions, reviews exponential notation, and addresses common misunderstandings. The tutorial compares exponential growth and decay, illustrating the process with function tables and graphs. It concludes by predicting when cesium-137 will decay below 100 kilograms, emphasizing that while decay is rapid initially, the substance never fully disappears.
