U.S. health-care expenditures have been growing exponentially during the past two decades. In 2008, expenditures were 2.4 trillion dollars with a growth rate of 9%. Lawmakers hope to decrease the annual growth rate to 2%. Compare the two rates graphically and algebraically as follows. (a) For each growth rate, find an exponential model for the health-care expenditures t years since 2008. f9%(t)  =        f2%(t)  =          (c) Find the predicted health-care expenditures in 2020 for each model. (Round your answer to two decimal places.) f9%(12)  =   trillion dollars f2%(12)  =   trillion dollars
