For each of the sets of data that follows, use the least squares approximation to find the best fits with both (i) a linear function and (ii) a quadratic function. Compute the error E in both cases.

(a) {(-3, 9), (−2, 6), (0, 2),(1, 1)}

(b) {(1, 2), (3,4), (5, 7), (7, 9), (9, 12)}

(c) {(−2, 4), (−1, 3), (0, 1), (1,−1), (2,−3)}
