Let P(x) and Q(x) be predicates and suppose D is the domain of x. In 5558, for the statement forms in each pair, determine whether (a) they have the same truth value for every choice of P(x), Q(x), and D, or (b) there is a choice of P(x), Q(x), and D for which they have opposite truth values. x D, (P(x) Q(x)), and (x D, P(x)) (x D, Q(x))

Please provide truth tables. Thanks!
