Write a function mirror that will receive one input vector consisting of y coordinates of data points. The function will fit a second-order polynomial through the points. The function will plot on one graph, the original data points (using green *s). the curve (using blue and with enough points so that it is very smooth), and also "mirror image" points |in red *s). The "mirror image" points are. for every x coordinate, equidistant from the curve as the original data point. So. if the original data point is 2 above the curve, the mirror image point will be 2 below it
