The table shows the annual revenue from area Walmart stores (in millions of dollars). Amount, y 12.92 Year 2003 2004 14.70 2005 16.18 2006 2007 17.64 18.70 2008 19.07 a. Use the regression feature of a graphing utility to find a linear model, an exponential model, and a logarithmic model for the data. Let x represent the year, with x= 3 corresponding to 2003. (Round all numerical values to four decimal places.) (If using Desmos, be sure "Log Mode" is selected) Linear Model is in the form y = az + b, where a = Number and b= Number %3D Its 2 = 0.9663 Logarithmic Model is in the form y = a +b In z. where a = Number and b= Number Its 2 = Number Exponential Model is in the form y = a(b), where a- Number and b= Number %3D Its r2 = Number b. How can the coefficients of determination be uséd to determine which model best fits the data? The model that is the best fit has a coefficient of determination that is closest to 1. c. Which model is worst Exponential O Linear O Logarithmic d. Use the BEST model to estimate the revenue in 2016. Round the answer to two decimal places.
