Exploring Exponential Functions and Sequences

The video tutorial reviews exponential functions and sequences, covering initial values, growth and decay factors, and real-world applications. It includes examples of population growth, value depreciation, and sequence identification. The tutorial also guides on writing sequence formulas and solving exponential problems.
