format of the answer for question 4 should be like this explain in example in another pic.

4. Prove or disprove the following statement using the definition of w notation. Do not use limits in your proof. 80n? +10Vnew(nlogn) Prove that n logn +n + log n e O(n log n). proof: (2) (3) by (2) and 7 A 7 Let M=3 Let no = 2 Choose any n > To n > 2 log n > log 2 log ni > 1 n logn >n n 1 ne logn > logn log n 0. Eno >0 s.t. Vn > no, n log n+n+log n
