Estimating Population Growth Time

The video tutorial explains how to determine when a population of bacteria will reach 5,000 using the equation P(t) = 1,000 * e^(0.12t). The instructor demonstrates solving this problem with a graphing calculator, utilizing both the table and graphing features. The solution is verified graphically by finding the intersection of the population function and a horizontal line at 5,000. The tutorial concludes with a note that logarithmic methods will be covered in future lessons.
