Alternatively, let me prove $U_4$ is a subspace by verifying it is closed under additon and scalar multiplicaiton explicitly. Closed under addition: ex. Show the Subset of the Vector Space of Polynomials is a Subspace and Find its Basis Let P3 be the vector space over R of all degree three or less polynomial 24/7 Live Expert You can always count on us for help, 24 hours a day, 7 days a week. A subset S of Rn is a subspace if and only if it is the span of a set of vectors Subspaces of R3 which defines a linear transformation T : R3 R4.
