Hello,

I have just finished the O-Notation course and searched the Internet for more exercises. What I have found was quite interesting, but also frustrating. Can you please help me with these?

My suggestions:

- O(n^4)
- O((1-1/2017)^5n)
- O(n^2)

.6. O(1.18n^2)

I’m not sure, but do I have to consider a negative integer for k?

Thanks!
