FIFB4 - Extension Problem
Influenza epidemicAn epidemic of influenza spreads through a city. The figure below is the graph of I=f(w), where I is the number of individuals (in thousands) infected w weeks after the epidemic begins.

- Estimate f(2) and explain its meaning in terms of the epidemic.
- 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.
- For approximately which w is f(w)=4.5; explain what the estimates mean in terms of the epidemic.
- An equation for the function used to plot the image above is 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.
