5.1 #1 The graph below shows a plot of the total number E of Ebola cases in West Africa reported to the Centers for Disease Control and Prevention from April 1, 2014 through December 1, 2015. A logistic model for these data is given by 27841.42 E = 1+ 134.65e-0.646t Where ț is the time in months since April 1, 2014. 28 000 # of cases of Ebola ++++++ 21 Time in months since April 1, 2014 a. Does the graph show a continuing epidemic or a health crisis that is under control by December 2015? b. According to the model, what was the total number of cases when the disease was spreading at the fastest rate? Round your answer to the nearest whole number.
