Exponential Functions and Their Properties

Shane compares the common ratios of two exponential functions, one given as an equation and the other as a verbal description. The video explains the standard form of an exponential function, highlighting the roles of variables and constants. It emphasizes the concept of the common ratio, which indicates the growth or decay factor. The video concludes by identifying the common ratios as 6 from the equation and 4 from the verbal description.
