Answer:
All of them.
Step-by-step explanation:
For rational functions, the domain is all real numbers <em>except</em> for the zeros of the denominator.
Therefore, to find the x-values that are not in the domain, we need to solve for the zeros of the denominator. Therefore, set the denominator to zero:

Zero Product Property:

Solve for the x in each of the three equations. The first one is already solved. Thus:

Thus, the values that <em>cannot</em> be in the domain of the rational function is:
