• its fasle as not always f(n)
• 9 years agoHelpfull: Yes(6) No(3)
• Sometimes True because if f(n)=1/n it is not true
• 9 years agoHelpfull: Yes(3) No(4)
• false...beacause f(n)^2=!f(N)

• FALSE
  Because even though it seems true for some functions like f(n)=1/n, it becomes false.
  1/n != O(1/n^2)
