I don't know these questions. These problems are LINEAR ALGEBRA.

8 '1 The table shows the revenue of a corporation (in billions of dollars) for Year 2008 2009 2010 2011 2012 2013 Revenue 29.3 32.0 32.5 32.7 31.7 31.2 Let :1: = 8 represents the year 2008 (i.e. :1: = year - 2000). Find the least squares regression quadratic polynomial y = co+clzr+62x2 for the data in the table and use your model to estimate the revenue for 2015. You will need to state the system of interpolating conditions and the normal system of equations as part of your solution, and then resolve the normal system for q. six different years
