Could someone answer these: Whether they are true or false: (Big O, Big Theta, Big Omega)

TRUE/FALSE 1. True 2. False and so on n 2 100 O(n) 2. n2+100 O(n2) 3. n2+100- O(n) 4. n2- 1,000, 000, 000 - O(n) 7. n2*n=0(n 2) 9. n2 + log(n)n2-O(n 2) 10. n2+log(n) n- O(n 2) 11. n2+100-on 4) 12. n2+100-?(n 2) 13. n2+100-?(n) 15. n+ 100.000 ?(n) 17. n2+n+100-0(n 2) 18. n2 +100 0(n 3) 19. n2*n+100-0(n 3) 20. 100 *n log(n) 0(n log n)
