I am an undergraduate student in Computer Engineering and going through one of the textbook examples, I am asked to prove that
$T(n)$ is $O(\log{}n)$
Where $T(n)= 5\log_{2} 2n +7$. I understand that this means that I must prove that $5\log_{2} 2n +7 \leq\lambda log(n)$
For some in n in a neighborhood of infinity. How exactly would I proceed with this?
