To identify the restrictions on the domain of a rational expression, you need to look for values that make the denominator equal to zero, as these values are not allowed in the domain (they would make the expression undefined).
If you've provided a specific rational expression but it appears as "Captionless Image," I cannot see or interpret images directly. If you can provide the expression in text format, I can help you identify the restrictions.
However, generally, if the rational expression is in the form of \( \frac{f(x)}{g(x)} \), you would set \( g(x) = 0 \) and solve for \( x \). The solutions are the restrictions to the domain.
If you have specific values (like -2, 4, etc.) listed in your options, those are likely candidates for potential restrictions. If any of those values cause the denominator to equal zero, they are indeed restrictions.
Please provide the actual rational expression, and I can give you a more precise answer!
