Linear Algebra:

Determine if the following set, W, is a subspace of P3, the vector space of all polynomials of degree
less than or equal to 3 with real coefficients. If it is a subspace, prove it. If it is not, explain why.
W is the set of all polynomials of degree at most 3, with integers as coefficients.
(hint: the set of integers is {...,-3,-2,-1,0,1,2,3...}. An example of a polynomial in this space is -2t³+4t²)

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.
