Let f(n) and g(n) be asymptotically positive functions. Prove or disprove each of the following conjectures. f(n) = O(g(n)) implies g(n) = Ω(f(n)) . f(n) = O(g(n)) implies g(n) = O(f(n)). f(n) + g(n) = Θ(min(f(n),g(n))).
Let f1 and f2 be asymptotically positive non-decreasing functions. Prove or disprove each of the following conjectures. To disprove give a counter example. If f1(n) = O(g(n)) and f2(n) = O(g(n)) then f1(n)= Θ (f2(n) ).
Let f1 and f2 be asymptotically positive non-decreasing functions. Prove or disprove each of the following conjectures. To disprove, give a counterexample. a.If f1(n) = Theta(g(n)) and f2(n) = Theta(g(n)) then f1(n) + f2(n) = Theta(g(n)) b.If f1(n) = O(g(n)) and f2(n) = O(g(n))then f1(n) = O(f2(n))
Let f (n) and g(n) be asymptotically nonnegative functions. Using the basic definition of _-notation, prove that max( f (n), g(n)) = Θ( f (n) + g(n)).
