The video tutorial explains how to interpret the exponential expression 2000 * 1.05 ^ x, which models a country's population over time. The focus is on understanding what the coefficient 2000 represents, which is the starting population at zero years. The tutorial evaluates different answer choices, confirming that the coefficient signifies the initial population, while other options are incorrect.
