For each of the following:
i. Write/expand each of the following predicates using disjunctions, conjunctions, and negations.
ii. Determine the truth value of the following statements.
P(x,y): x < y^3
Q(x,y): x –1 > y^2
R(x,y,z): x + y^3 > z
Universe of discourse for variable x is N (natural numbers)
Universe of discourse for variable y is Z+ (positive integers)
Universe of discourse for variable z is R+ (positive real numbers)
I understand the problem except that in the discrete book the problems always give a set of particular numbers to use the conjunctions, disjunctions, and negations on.
