Answer:
The denominator is all real numbers except 0.
Step-by-step explanation:
In the function f(x) = 1/x, x appears in the denominator. A denominator cannot be zero since division by zero is undefined.
To find what values of x must be excluded from the domain, set the denominator equal to zero, and solve for x.
x = 0
The denominator is all real numbers except 0.
