Final answer:
In mathematics, the domain of a function is the set of all possible values of the independent variable, while the range is the set of all possible values of the dependent variable.
Step-by-step explanation:
In mathematics, the domain of a function is the complete set of inputs, or the set of all possible values of the independent variable. On the other hand, the range is the set of all outputs, or the set of all possible values of the dependent variable.
For example, consider the function f(x) = x^2. The domain of this function is all real numbers because any real number can be squared. The range, on the other hand, is the set of all non-negative real numbers because a square of a real number can never be negative.
