Problem 4. Suppose L: V → W is a linear map, with L(V) = W. Prove that if {ū1, ..., ūn} is a spanning set of V, then {Lū1, ..., Lūn} is a spanning set of W.
(4) Let V and W be vector spaces over R: consider the free vector space F(V × W) on the Cartesian product V x W of V and W. Given an element (v, w) of V x W, we view (v, w) as an element of F(V x W) via the inclusion map i : V x W F(V x W) Any element of F(V x W) is a finite linear combination of such elements (v, w) Warning. F(V ×...

Q4. Let T :V + W be a one-to-one linear transformation (i.e. an equation T(u) = T(v) always implies u = v). (a) Show that the kernel of T contains only the zero vector.
