I need to order the following: 10n + 5 + 2n 20n log n + 2345 3 log n + 5n2 100 log n + 5000 from the slowest growing function to the fastest growing function and to be fair I don't have a clue; can some one help please?

If differentiable function f(n) is growing faster than differentiable function g(n), what can you say about f'(n) and g'(n)? Furthermore, you do realize that one function may grow faster than another in part of their mutual domain and may grow more slowly in a different part of their common domain. What does your problem say about domains?
