Knowing that `O(n^2) > O(nlogn) > O(n) > O(sqrt(n)) > O(logn) > O(1)`

and having below python code:

`import math def f1(n=9): return math.sqrt(n) def f2(n=10): return [math.sqrt(i) for i in range(n)] `

- Am I correct to infer that
**O(f1(n)) = O(1)** - Am I correct to infer that
**O(f1(n)) = O(n)**
