Question 14

As we approaching from the negative side,
|x-3|=3-x.

So, we have
\lim_(x \to 3^(-))=(3-x)/(x-3)=(-(x-3))/(x-3)=\boxed{-1}

and thus the limit exists at x=3.

Question 15

For the top part of the function,
(9-9)^(2)=0

For the bottom part of the function,
9-9=0

As both one-sided limits are equal, L = 0, and thus the limit exists at x=9.
