From 2002 to 2016, the age-adjusted incidence rate of invasive lung and bronchial cancer among women can be closely approximated by ƒ(t) = -0.0723t² + 0.723t + 52.0, where t is the number of years since 2000. Based on this model, in what year did the incidence rate reach a maximum? On what years was the rate increasing? Decreasing? Source: National Cancer Institute.
