What is domain in math definition. For f x x 2 the domain in interval notation is. The set of actual output values is called the range or in other words the set of values that the output values lie in. Usually domain means domain of definition but sometimes domain refers to a restricted domain. To find the domain of this function we need to remember the definition of a domain and then do simple algebra.
