Sorry, I decided to post this question again because I typed wrong before. Also could you guys please help me with these 2 limits questions. I tried doing them but my answer was wrong. Could you guys please show full working out and solutions.

14. f(x) = x+2/x-3 at x=1

4. lim
x->root 3 root 3x - x / 3 -x^2

5. lim
x->root a x^2 - a / x+ root a

Thanks
