8. (adapted from II.2 20) In this problem we will fit a quadratic function b = 20t + Dt + Et- to measurements b = 0,3, 5,6 at times t = 0, 1, 2,3, respectively. (a) Formulate this problem as a linear squares problem min | Ax - b|, (i.e., show A, x, b). (b) Solve for the x that minimizes | Ax - bl|2. (c) Does this least squares problem have a unique solution?
