2. (a) Explain what is mean by a linearly independent set of vectors. For which values of k is the following set of vectors linearly independent? {(1, 3, 3, 1), (2, 0, 1, 9), (0, 0, 4, 3), (k, k, −4,4)} (b) What is meant by a basis for a subspace of R"? Find bases for each of the following subspaces of R³ (there is no need to show that they are subspaces): (i) {(a 2b, a + 3b, 4b): a, b ≤ R}; (ii) {(x, y, z) = R³ : x - 2y - 6z = 0}.
