I'm still kind of not sure how to answer these ...I know that a domain is a set of integers for example and the functions are P(x) and Q(x) and we make an equation to suit it answering A ∩ B = Ø and A ⊆ B butA ≠ B.

c)x ∈ A - B, what is the truth value of Q(x) means the truth table is drawn up with P , Q and P ∩ Q ?

and

d) x ∈ A - B, what is the truth value of P(x)V ¬Q(x)? means the truth table is drawn up with P, Q ,¬Q and P/¬Q ?

Is that correct for my truth tables..?

I better go to bed too much math has killed my brain thanks
