Answer #1

31459+lg(n)= O(lgn), since lg(n) will have higher growth than const value

0.5 f2 3n-lg(lg(n))+n=0(n), since n will have higher growth than lower n power and log functions 7

f3 4nn2n2/8-1.5n 0(nn)

f41.2 -0.8 2n2 0(1.2)

The growth rate of exponential increasing function is faster than polynomial functions

f53n-2n24n 5 0(n)

The highest order function polynomial is n^3 in this case

f=nlg(n)-lg(n) 4nlg(n) 31g(n) = 0(nlgn)

Now, the order will be

35
