b.

Step-by-step explanation:

You have fractions. Fractions don't output if the denominator is 0 because you cannot divide by 0.

So 2/x^2 and 13/x^2 have issues when x=0 because it leads to 2/0 and 13/0 respectively.

The domain is all real numbers except x=0.

An equivalent way of saying that is all non-zero real numbers.
