Question 6 Recall: Let P (x) and Q(x) be predicates and suppose that the common domain of x is D. VED, P(x) →→→ Q(x) means that every element in the truth set of P(x) is in the truth set of Q (x). • VxD, P(x) Q (x) means that P(x) and Q(x) have identical truth sets. For each bulleted sentence, draw a venn diagram representing the relationship between the domain D, the truth set of P (x), and the truth set of Q(x). Label each diagram with the bulleted statement it represents. Then take a picture of each venn diagram and embed it in the textbox as your response to this question.
