Exponential Functions Mastery Challenge

This video tutorial covers the basics of exponential functions, focusing on their equations, graphs, and characteristics. It explains the concept of y-intercept and growth rate, comparing functions with different growth rates. The video also introduces exponential decay, highlighting how functions decrease when the growth rate is between 0 and 1. Key concepts such as horizontal asymptotes and the behavior of exponential functions are summarized.
