Let f(n) and g(n) be positive functions. Which of the following is sufficient to show that f(n)/O(g(n)) ? Let M>0 and n0>0 be arbitrary. Show that if n=n0+M+10, then f(n)>Mg(n). Let n0>0 be arbitrary. Show that if n=n0+5, then f(n)>g(n). Show that for all n>45,f(n)>5g(n). Let M>0 be arbitrary. Show that if n>M+2, then f(n)>3g(n)
