Post your question.
Edit: on phone didn't show before. What exactly do you need help with? These are simple limit problems plug in numbers close to limit and get what the function approaches to.
After looking at picture all the above limits are simple. Look at the left handed limit and the right handed limit, if those numbers are not equal then your limit does not exist for the function, if they are it does exist and that is the limit. Secondly, your functions are continuous on all but the point asked in the limit because if you look that is the point of discontinuity of the function (check this by solving denominator when set equal to zero).
Pm me if you need further help.
