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. Use the formal definition of Big-Oh to prove that if f(n) = 0(g(n)) and g(n)...

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")
