in MATLAB Curve fitting Given the following data, find the best linear functional relationship and cubic functional relationship using “polyfit,” “polyval,” and “plot” built-in functions. Plot all three fits that you got from Matlab. A rough plot by hand is allowable. You do not need to provide any codes. x = [-3, -2, 0, 1, 3, 4, 6, 7, 8, 9]; y = [5, 7, 8, 10, 6, 2, -4, -6, -2, 1];
