Let W be a vector space. (i) Suppose that U₁ and U₂ are both subspaces of W. Show that the intersection U₁n₂ is also a subspace of W. (ii) Let g: W → W be a linear map such that go g is the zero map. (That is, g(g(w)) = 0 for all we W.) Show that im g ker(g). (iii) =h(w₂) Let h: W→ W be a linear map. Show that h is injective (that is, h(w₁) = only when w₁ = W₂) if and only if ker(h) = {0}.
