In each of the following, determine if the given set is a subspace or not.
For each case in which the set is a subspace, verify that it is a subspace by showing that subspace properties (SO), (S1), and (S2) hold.
For each case in which the set is not a subspace, state one of the properties of a subspace that does not hold and give a counterexample showing that the
property fails.
