What are the domain and range for the function y equals negative square root of x minus four end square root minus three?

Answer 1

The domain of a function is the complete set of possible values of the independent variable. In plain English, this definition means: The domain is the set of all possible x-values which will make the function "work", and will output real y-values.
domain x >= 4
range y <= -3
