Do the invertible 3 × 3 matrices form a subspace of M 3 × 3 ? 2 What about the matrices of the form a b c d e f ? Of the form a b c 1 d e 1 1 f ? 4. Consider the transformation T : P 3 → P 3 given by T ( p ) = p . Prove that T is a linear transformation and determine if it is 11 and if it is onto. 5. Let A be some ﬁxed 2 × 3 matrix. Prove that the set { B ∈ M 4 × 2 : AB = 0 } is a subspace of M 4 × 2 . 1 P n denotes the set of all polynomials with degree less than or equal to n 2 M m × n denotes the set of all m × n matrices...
