Expert Solution

4.) loving f(n) = n² + 3n + lg(n);

a.) Control f(n) = O(n²); c*n²>= f(n); control complete n, where c>0 and n>=n₀

So control c=100 and n₀ = 1; f(n) = O(n²).

b.) Control f(n) = big-omega(n²); c*n²<= f(n); control complete n, where c>0 and n>=n₀

So control c=1 and n₀ = 0; f(n) = big-omega(n²).

c.) Control f(n) = big-theta(n²); c₁*n² <= f(n)<= c₂*n²; control complete n, where c₁ and c₂ >0 and n>=n₀

Since, f(n) = O(n²) as well-mannered-mannered as f(n) = big-omega(n²). Therefore, f(n) = big-theta(n²)

5.) loving f(n) = n;

control f(n) = o(n); c*n > n where c>0;

so control no appreciate of c>=1; we can terminate overhead state. Hence, f(n) is referable similar to o(n).

Hope it helps, feels untrammelled to illustrate in contingency of any inquiry.
