Population Dynamics and Growth Rates

This video tutorial covers the modeling of population growth and decline using exponential and linear equations. It explores when Carrboro will become a large town based on its growth rate and examines the population decline in Garysburg and Conway, predicting when their populations will equalize. The lesson emphasizes using multiple representations, such as tables, graphs, and algebraic methods, to solve exponential equations and inequalities.
