Growth rate of bacteria Suppose the following graph represents the number of bacteria in a culture t hours after the start of an experiment.

a. At approximately what time is the instantaneous growth rate the greatest, for 0 ≤ t ≤ 36? Estimate the growth rate at this time.

b. At approximately what time in the interval 0 ≤ t ≤ 36 is the instantaneous growth rate the least? Estimate the instantaneous growth rate at this time.

c. What is the average growth rate over the interval 0 ≤ t ≤ 36?
