An invalid argument is given below. 3x (P(x) ^ ¬Q(x)) (Q(x) → P(x)) -P(X) The domain of x is the set of positive integers. Select a definition for each predicate P and Q that proves that the argument is invalid. P(x): x is even x is composite x² < x Q(x): x is odd x is a multiple of 4 x is prime An invalid argument is given below. 3x (P(x) ^ ¬Q(x)) (Q(x) → P(x)) -P(X) The domain of x is the set of positive integers.
