1. Let P(x) be the predicate a > x a. Write P(2), P(), and P(-2). Indicate which of these statements are true and which are false. b. Find the truth set of P(x), that is, the largest subset of the domain of P for which P is true. c. If we restrict the domain of P to be the set of all positive real numbers, what is the truth set of P?
