Exercise 2. True or False (give a counterexample when False) a. The vectors b that are not in column space C(A) form a subspace. b. If C(A) contains only the zero vector, then A is the zero matrix. c. The column space of 2A equals the column space of A. d. If A is a square matrix, the column space of A – I equals the column space of A.
