Determining Limits 
The Question above states determine the limits, for problem a) I evaluated for when lim x->2 instead of 4. This was marked wrong im simply asking for a clarification on what the question is asking me to do. 

It is $not$ the answer to any of the questions, but yes it most likely is the points awarded to each question, with $6$ being the hardest question. You evaluated the limit incorrectly, that's why you lost points. If you got $\sqrt{18}$ for the first limit, you would've got $4$ marks
