Web9 jun. 2024 · 1. In general an affine subspace is not a subspace, it's just a translate (coset) of a subspace. This is because normally we expect 0 to be in a subspace V, since due to closure x − x ∈ V. If a + V is an affine subspace for a ≠ 0, and V a subspace then automatically a is required to be not in V. Otherwise a + V = V. WebHomework help starts here! Math Advanced Math Determine whether the set S spans R2.
