All real numbers except -13 and 13.
All real numbers except 16.

Answer 1

All real numbers except 13

Answer 2

Explanation:

Domain is the set of all values of x where the function is defined. For this function the only limitation upon x exists when the denominator would equal zero, because division by zero is undefined. So the denominator 13-x cannot equal zero thus x cannot equal 13. Thus the domain is all real numbers except 13.
