(a) What is the average rate of change of the number of flu cases between 2 weeks and 5 weeks? (Round your answer to the nearest whole number.)
cases/week
Enter a number
(b) Write a sentence that explains the meaning of the average rate of change in the context of this exercise. (Round your answer to the nearest whole number)
Because the average rate of change is positive
the number of flu cases was increasing by an average rate of
weeks after measurements began.
X cases per week between 2 and 3
