Constant Percentage and Exponentials
Constant percentage growth, inherent in exponential functions, underpins various phenomena across disciplines from finance to population dynamics. Exponential growth or decay occurs when a quantity increases or decreases by a fixed percentage over a constant interval. This fundamental concept is pivotal in understanding diverse real-world processes, including compound interest, population growth, and radioactive decay. By exploring the interplay between constant percentage growth and exponential functions, we unravel the dynamics of systems evolving over time. Understanding these principles equips us with valuable insights into predicting trends, making informed decisions, and comprehending the underlying mechanisms driving exponential phenomena.
