To identify the restriction to the domain of a rational expression, we need to determine where the denominator equals zero since a rational expression is undefined when the denominator is zero.
Assuming you have a rational expression in the form \( \frac{f(x)}{g(x)} \), you would set \( g(x) = 0 \) and solve for \( x \) to find the values that are not included in the domain.
From the options you provided (-7, -5, -7/5, 0), we need to check if any of these would make a hypothetical denominator equal to zero.
However, without the actual rational expression (the numerator and denominator), I cannot directly compute the specific restrictions.
Please provide the rational expression so I can accurately identify the restrictions to the domain.
