I got this assigned for homework for an online calculus course, while I've been doing fine searching the internet and using examples, and I understand a bit I have doubts in certain things.

For the function f whose graph is shown, state the value of the
given quantity, if it exists. If it does not exist, explain why.

I'm not looking for answers as I'd like to learn this and I'm not here to cheat or make other people do my work but plead for help instead. What bothers me about this question is there is no function and the fact that some points the line do not go through or have a point saying that it ends where it does. I'm not gonna put all the questions, just the ones I'm a bit iffy about, and what I think the answer is or need to be confirmed.

was asked to edit out my answers.

I appreciate the help as always - thanks!
 
You are correct in your answers.
However, some texts might expect \(\displaystyle -\infty\) as an answer for part a.
