Exponential Growth and Population Dynamics

The video tutorial explains exponential growth using Euler's number, with a focus on population growth. It provides an example of a town in Idaho growing at 4.5% annually. The exponential growth equation is introduced and used to calculate the town's future population in 20 years. The tutorial highlights the importance of this calculation for city planning, as the population is expected to more than double. The lesson concludes by emphasizing the simplicity and utility of the exponential growth equation.

What is the primary focus of the video tutorial?
