Exploring Exponential Functions: An Introduction

This video introduces exponential functions, contrasting them with linear functions. It explains how linear functions involve constant addition, while exponential functions involve multiplication, leading to growth or decay. The video covers identifying initial values and growth or decay factors, using examples to illustrate these concepts.
