1. Consider a set of four data points: f(0) = 3, f(4) = -2, f(-1) = 2, and f(1) = 1. In the following, use these data points to find the best fit polynomial of degree 2 by using the QR-decomposition method: (d) Compute Re and QTb, where x = (ao a₁ a2)T which are the coefficients of the polynomial p2(x). Using the above result, find the values of ao, a₁ and a2, and write the polynomial p2(x).
