Let W be a subspace of R4 spanned by the set Q = {(1,-1, 3,

Let W be a subspace of R4 spanned by the set Q = {(1,-1, 3, 1), (1, 1,-1,2), (1, 1, 0, 1)}. (i) Show that Q is a basis of W. (ii) Does the vector u = (-4, 0, -7, -3) belong to space W? If that is the case, find the coordinate vector of u relative to basis Q.
