Consider the following W subspace and given vector x in the R vector space: W = Span{1, 1, -1, 1, 3, 1, 2, 2, 3, -3, 3, -1} x = 4, 7, 7, -8 (a) (2 points) Decide if the generator system of W is an orthogonal system or not. (b) (8 points) Give an orthogonal and an orthonormal basis in the W subspace. (c) (4 points) Decompose vector x into a parallel and an orthogonal component regarding subspace W.
