Introducing Calculus Practice Test

Divide 50,000 cells by the total time it took for the population to reach that size from the start.

Assume the growth rate is constant and equal to the average rate observed during the first hour of growth.

Measure the population one hour before and one hour after it reaches 50,000 and find the average rate.

Calculate average growth rates over increasingly small time intervals around that moment and find their limiting value.
