Question
The problem given is:

"The domain of the function \( f(x) = \frac{26}{2x - 30} \) is all real numbers \( x \) except for \( x \) where \( x \) equals"

**Explanation:**

This question requires determining the domain of the rational function \( f(x) = \frac{26}{2x - 30} \). The domain of a function is the set of all possible input values (in this case, \( x \)) that will produce a valid output. 

For rational functions, any values of \( x \) that make the denominator zero are excluded from the domain. Therefore, we need to solve for \( x \) when the denominator \( 2x - 30 = 0 \).

**Solution:**

1. Set the denominator equal to zero:  
   \( 2x - 30 = 0 \)

2. Solve for \( x \):  
   \( 2x = 30 \)  
   \( x = 15 \)

Thus, the domain of the function is all real numbers except \( x = 15 \).

**Note:**
