Growth and Decay Equations

The video tutorial explains how to complete a table with exponential functions, focusing on identifying growth and decay equations. It covers the calculation of decay and growth rates, converting them to percentages, and constructing equations from given data. The tutorial provides detailed examples for each row of the table, illustrating the process of determining B values and initial values for both growth and decay scenarios.
