Is W a subspace of the vector space? If not, state why. (Select all that apply.) W is the set of all vectors in R2 whose components are rational numbers. W is a subspace of R2. W is not a subspace of R2 because it is not closed under addition. W is not a subspace of R2 because it is not closed under scalar multiplication.

Branch of mathematics concerned with mathematical structures that are closed under operations like addition and scalar multiplication. It is the study of linear combinations, vector spaces, lines and planes, and some mappings that are used to perform linear transformations. Linear algebra also includes vectors, matrices, and linear functions. It has many applications from mathematical physics to modern algebra and coding theory.
