Question $1$

The function $f(n)=4n+3logn$ belongs to the $O(n)$ time complexity because:

the $(n)$ term is the first term in the function

This statement is False. This function belongs to the $O(n+logn)$ time complexity

there is only an $(n)$ term and a $(logn)$ term, and there cannot be a O $(logn)$ time complexity

the $(logn)$ term is absorbed into the $(n)$ term for the time complexity
