- Suppose that φ : V1 → V2 is a linear mapping. Then U = φ(V1) is a subspace in V2. If φ is one-to-one, then dimF U = dimF V1. If, in this case, dimF V1 = dimF V2 < ∞, then U = V2 and the mapping φ is an isomorphism. prove itA subspace U of R^2 is a subset which satis es three properties: A) 0∈U, B) U is closed under addition, and C) U is closed under scalar multiplication. Give subsets UA, UB and UC of R^2 so that UA satis es only B and C, UB satis es only A and C and UC satis es only A and B.Determine whether the following are subspaces of P4 (be careful!): The set of polynomials in P4 of even degree
