Which of the following subsets are subspaces of the speciﬁed vector space V? For each part, either verify closure under the necessary operations or show that at least one of the two closure properties fails. a) S1 = {(x1, x2, x3)T |x2 − x1 + x3 = 0}, in V = R3. b) S2 = {(x1, x2, x3)T |x1 = x3}, in V = R3. c) S3 = {(x1, x2, x3)T |x1 · x2 = 0}, in V = R3.
