Given that P(x, y, z) is a propositional function such that the universe for x, y, z is {1,2}. Furthermore, suppose that the propositional function is true in the following cases, namely: P(1, 1, 1), P(1, 2, 1), P(1, 2, 2), P(2, 1, 1), P(2, 2, 2); and it is false, otherwise. Therefore, deter- mine the truth value of each of the following quantified statements, viz: (a) \x\y³zP(x, y, z) (b) Vx³y³zP(x, y, z) (c) VzxP(x, y, z) (d) xyz(x, y, z)
