The data can be modeled by the function f(x) = 1.2lnx + 15.7, where f(x) is the percentage of the U.S. gross domestic product going toward health care x years after 2006. Use this information to solve Exercises 115-116. 115. a. Use the function to determine the percentage of the U.S. gross domestic product that went toward health care in 2009. Round to the nearest tenth of a percent. Does this underestimate or overestimate the percent displayed by the graph? By how much? b. According to the model, when will 18.5% of the U.S. gross domestic product go toward health care? Round to the nearest year.
