Textbook Question
Chapter 3.6, Problem 47PE
During a recent outbreak of Ebola in western Africa, the cumulative number of cases y was reported t months after April 1. (See Example 7)
a. Use a graphing utility to find a model of the form
b. Write the function from part (a) as an exponential function of the form
c. Use either model to predict the number of Ebola cases 8 months after April 1 if this trend continues. Round to the nearest thousand.
d. Would it seem reasonable for this trend to continue indefinitely?
e. Use a graphing utility to find a logistic model
f. Use the logistic model from part (e) to predict the number of Ebola cases 8 months after April 1. Round to the nearest thousand.
