The video tutorial explains how to model the growth of bacteria using a continuous exponential growth function. Starting with 1,000 bacteria growing at a rate of 16% per day, the tutorial demonstrates how to set up the function P(T) = P0 * e^(kt), where P0 is the initial amount, k is the growth rate as a decimal, and T is time in days. The tutorial then applies this function to determine the number of bacteria after 30 days, using a calculator to evaluate the expression, resulting in approximately 121,510 bacteria.
