Find the domain of the function. write your answer as an inequality. or, you may instead write "empty set" or "all reals" as the answer.

Domain is the set of numbers for x we can plug in for this function .

Here x is inside redical sign but there it is " -x "

we know that sqrt of a negative number is an imaginary value

so we need to avoid such values of x which gives a negative value inside redeical .

the term inside redical should be equal or greater than 0 only

so -x >= 0

that means x <= 0

so domain is : all negative real numbers + 0

Answer : (- inifnity , 0]
