Chapter 2, Problem 2.1.35(choose chapter or problem)
An epidemic of influenza spreads through a city. Figure 2.6 is the graph of I = f(w), where I is the number of individuals (in thousands) infected w weeks after the epidemic begins. (a) Evaluate f(2) and explain its meaning in terms of the epidemic.(b) Approximately how many people were infected at the height of the epidemic? When did that occur? Write your answer in the form f(a) = b. (c) Solve f(w)=4.5 and explain what the solutions mean in terms of the epidemic. (d) The graph used f(w)=6w(1.3)w. Use the graph to estimate the solution of the inequality 6w(1.3)w 6. Explain what the solution means in terms of the epidemic.
