Big O Proof , f(n) = 2n + 1 and I have to prove f(n) is O n^2
If I have $f(n) = 2n + 1$ and I have to prove $f(n) \in O(n^2)$, by proving there exists positive constants $c$ and $n_0$ such that $f(n)<cn^2, \forall n\ge n_0$, can I do this all in one step by put …

How to prove Big-O when $f(n)$ is defined sectionwise
I'm given a function which is defined based on a condition, for example
$$
f(n)
= \begin{cases}
4n+1, \ \text{n is even}\\
3n^2+2, \ \text{n is odd}
\end{cases}.
$$
I have to prove or di …
