Please help with the following in Time Complexity. 1)Show that the following order-of-magnitude results hold: a)3n=O(n!) b)(n3 -2n)/(n+1)=theta(n2) c)n3 /log(n+1)=O(n3) but not O(n2) 2)What is wrong with the following argument? x=O(n4),y=O(n2),therefore x/y=O(n2). 3) What is wrong with ... with the following argument? f(n)=O(n2)+O(n), so that f(n)-g(n)=O(n2 )+O(n)-O(n2). Therefore, f(n)-g(n)=O(n)
