Formal Definitions of Big-Oh, Big-Theta and Big-Omega:
1. Use the formal definition of Big-Oh to prove that if f(n) is a decreasing function, then f(n) = 0(1). A decreasing function is one in which f(x1) f(r2) if and only if xi 5 r2. You may assume that f(n) is positive evervwhere Hint: drawing a picture might make the proof for this problem more obvious 2.

1. Write each of the statements using variables and quantifiers: a) Some integers are perfect squares. b) Every rational number is a real number. 2. Let P(x) = "x has shoes", Q(x) = "x has a shirt", and R(x,y) = "x is served by y". The universe of x is people. Rewrite the following predicates in words: a) ∀x∃y [(¬P(x) ∧ Q(x)) ⇒ ¬R(x,y)] b) ∃x∃y [(¬P(x) ∧ Q(x)) ∧ R(x,y)] c) P("Bill" ) ∨ (Q("Jim") ∧ ¬Q("Bill")) ⇒ R("Bill","Jim")

5. (2 point) For each of the following statements, write it in symbolic form using quantifiers. Then, determine whether the statement is true or false. Justify your answer. (a) Each integer has the property that its square is less than or equal to its cube. (b) Every subset of N has the number 3 as an element. (c) There is a real number that is strictly bigger than every integer.
