What are the values of a, b, and c the quadratic equation 0 = 1/2 * x ^ 2 - 3x - 2 a = 1/2, b = 3c = 2 =2 a = 1/2, b = - 3 c = - 2 a = 1/2, b = 3 ,= -2 c = - 2 a = 1/2, b = - 3 2 c = 2

The customer price index(cpi), which measures the cost of a typical package of customer goods,was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely.use data points to find such a line and then estimate the requested quantities
