Computer-controlled machines are used to cut and to form metal and other materials when manufacturing products. These machines often use cubic splines to specify the path to be cut or the contour of the part to be shaped. The following coodinates specify the shape of a certain car’s front fender. Fit a series of cubic splines to the coordinates, and plot the splines along with the coordinate points.
