Linear 2 step by step solution needed

(a) Let A be a 6-by-6 matrix. Suppose that (A -/) =0. Suppose that the nullspace of (A - I) has dimension 3. Write down the possibilities for the Jordan normal form of A. [6 marks] (b) Let A be an n-by-n matrix and let J = J,,(0). Suppose that AJ = JA. Prove that A = f(J) for some polynomial f. [6 marks]
