Exponential and Logarithmic Functions

The video tutorial covers exponential and logarithmic functions, starting with a review of polynomial functions and their growth patterns. It introduces exponential functions, highlighting their rapid growth compared to polynomial functions, and defines their properties. The tutorial then explains logarithmic functions as inverses of exponential functions, detailing their properties and examples. It also covers the properties of logarithms, including the base change rule and product rule. Finally, the video discusses the derivatives of exponential and logarithmic functions, using the chain rule for differentiation.
