least square problem

Given a training set {(1, -1), (0, 3), (2, -1)}, where in each pair the 1st and 2nd values are the attribute and target, respectively, answer the following questions: a. Specify the LSP for the above training set using non-matrix notation. b. Solve the LSP in Problem a using non-matrix notation. c. Repeat Problem a using matrix notation. d. Solve the LSP in Problem c using matrix notation.
