The domain of the function is the set of values of the variable for which the function has a value.
can be calculated as a real number in all cases where
<---> .
If <--> you cannot calculate the square root as a real number.
So the domain of is all the real numbers that are greater than or equal to 3.
Maybe you are expected to write it as
{x | } or some such thing.
Maybe the notation expected is

.
