Find and Use an Exponential Model to Find Inputs and Outputs Use Regression to Find and Use an Exponential Model to answer the questions The numbers of polio cases in the world are shown in the table for various years. Year Number of Polio Cases (thousands) 1988 1992 1996 2000 2005 2007 Let f(t) be the number of polio cases in the world t years since 1980. Use a graphing calculator to draw a scattergram of the data. Is it better to model the data by using a linear or exponential model? Select an answer Find an equation of f. Hint f(t) = 350 138 35 4 3.2 1.3 = (Round to 2 decimal places.) The number of polio cases is Select an answer by Select an answer per year. Predict the number of polio cases in 2014. Hint (Round to the nearest whole number.) Predict in which year there will be 1000 cases of polio. Hint (Round to the nearest year.) Find the approximate half-life of the number of polio cases. Hint years (Round to one decimal place.)
