7 Graph the following data, and then fit and graph polynomials of degree

and

All graphs must be on the same set of axes. Which fit seems best?

The MATLAB command pinv(A) computes A†, the pseudoinverse. The MATLAB statement pinv(A)*b computes the solution to a least-squares problem. For each part, you are given a least-squares problem. Solve each problem two ways, using one of the functions developed in this chapter and by using pinv.
