In mathematics, the domain of a function is the set of all possible input values for which the function is defined. On the other hand, the range of a function is the set of all possible output values. When dealing with square root functions, it's essential to understand the concept of domain and range, as the square root of a negative number is not defined in the real number system.

Understanding the Domain of Square Root Functions

The domain of a square root function is the set of all possible input values for which the function is defined. In other words, it's the set of all possible values of x for which the expression inside the square root is non-negative. This is because the square root of a negative number is not defined in the real number system.
