You haven't posted a function, but I'll provide an example of domain in set-builder notation.
The function has the domain since x = 2 leads to a division by zero error. Any other x value will work.
The notation shown above translates to "The domain is x such that x is a real number and "

Another example:
has the domain
If x = 5 or larger, then the stuff under the square root (aka radicand) is nonnegative.
If x < 5, then the radicand is negative, leading to f(x) outputs to be nonreal complex values.
