Writing Exponential Growth Functions for Percent Increase

The video tutorial explains exponential growth by interpreting percent increase as a growth factor. It uses a bacteria population example to illustrate how exponential growth occurs through repeated multiplication. The tutorial then transitions to financial examples, explaining how a 3% increase in savings is modeled as a growth factor of 1.03. It further demonstrates how to write an exponential growth equation for a savings account with 2% interest, emphasizing the importance of defining variables in such equations.
