- I. Let P (x) be the statement “2x = x2 .” If the domain consists of the integers, what are the truth values? a) P(0) b) P(1) c) P(2) d) P(−1) e) ∃x P(x) f ) ∀x P(x) 2. Let Q(x) be the statement “x > x - 1.” If the domain consists of all integers, what are the truth values? a) Q(10) b) Q(−2) c) Q(999) d) ∃x Q(x) e) ∀x Q(x) f) ∃x ˺Q(x) g) ∀x ˺Q(x)For (∃ x)(P(x,b)) Would an example of this being true if the domain was all the Avengers and x was green skin, then "b" being the Hulk would make this true. Am example of this being false would be: If the domain was all integers and x was positive, even integers and "b" was integers greater than zero.Let p and q be the propositions “Swimming at the New Jersey shore is allowed” and “Sharks have been spotted near the shore,” respectively.
