Step 1
A subspace is a subset of a vector space that is itself a vector space under the inherited operations from the larger vector space. This means that if W is a subspace of a vector space V, then W must satisfy all the properties of a vector space, including closure Show more…

Either use an appropriate theorem to show that the given set, W, is a vector space, or find a specific example to the contrary. W = {[c - 2d; d; c] : c, d real} Let w = [c - 2d; d; c]. Then w is an element of W. Write w in parametric vector form. w = c[1; 0; 1] + d[-2; 1; 0] (c, d in R) Now write the expression found for w in the previous step as the product of a matrix, A, and the vector [c; d]. w = A[c; d] w = [ ][c; d] Therefore, the set W = [ ] The [ ] of an m x n matrix A is a subspace of R^m. The proof is complete since W is a subspace of [ ]. The given set W must be a vector space because a subspace itself is a vector space.

Proof Let $W$ be a subspace of the vector space $V$. Prove that the zero vector in $V$ is also the zero vector in $W$.
