The table below gives the retail sale of electricity (in billions of kilowatt-hours) for the residential and commercial sectors of the United States. Yeara Residential (billions of kilowatt-hours)a 2000a 1,192a 2003a 1,276a 2006a 1,400a 2009a 1,420a 2012a 1,402p 2015a 1,390a Let xx represent time (in years) with x=0x=0 corresponding to 2000, and let yy represent the corresponding residential sales. Find the quadratic regression equation for the data y=R(x)=ax2+bx+cy=R(x)=ax2+bx+cq with aa rounded to the nearest hundredth (2 decimal places), bb rounded to the nearest tenth (1 decimal place), and cc rounded to the nearest integer. 1 Use the regression model found above to predict the instantaneous rate of change in residential retail sale of electricity in 2023. Round to the nearest billion of kilowatt- hours. NOTE: You may get the wrong answer if you do not use the quadratic model with coefficients rounded as described above. billion of kilowatt-hours per year
