Find an appropriate parametrization for the given piecewise-smooth curve in double-struck R2, with the implied orientation. The curve C, which goes along the circle of radius 3, from the point (3, 0) above the x-axis to the point (−3, 0), and then in a straight line along the x-axis back to (3, 0).

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
