1. Find a polynomial function to model the profit( in billions of dollars) for Intel Corporation based on the data collected below from the time period from 2004-2012. Find the quartic polynomial function to model the data using quartic regression (QuartReg) on your graphing calculator or use EXCEL. Assume that x = 4 corresponds to the year 2004 and profit, P(x), is in billions of dollars. 15 12.94 12.5 11.46 11.01 10 8.66 7.52 Net income in billion U.S. dollars 7.5 6.98 5.04 5.29 5 4.37 2.5 2004 2005 2006 2007 2008 2009 2010 2011 2012 a) Write the polynomial function, P(x), derived using regression (rounding coefficients to three decimal places) to develop a model for profit for Intel Corporation
