The data in the table give sales revenues and costs and expenses for Company X for various years. Use this table to answer the following questions. Cost and Expenses Year Sales Revenue (millions $) (millions $) 2003 2.4225 2.0121 2004 2.7575 2.4315 2005 2.9332 2.6257 2006 3.7512 2.8023 2007 3.9768 3.5400 2008 4.5485 3.8231 2009 4.7225 4.0321 2010 5.1668 4.8500 2011 4.9600 4.9523 2012 5.0927 4.6871 2013 4.6223 5.3110 2014 4.5012 5.6321 2015 3.8853 6.7423 a) Using the data set in the table, model Sales Revenues, R(x), as a quadratic function of year, with x=0 representing 2000. That is, plot this set of data and find the curve of best fit. (Use Excel) (Hint: replace 2003 with x-3, 2004 with x=4, and so forth before plotting the graph and finding the best fit curve. Review "Module 1-Excel Applications" notes.) b) Use the function R(x) you found in part a to determine the year (round to the nearest integer when necessary) in which the maximum revenue occurs, and then compare this value
