Domain And Range Math Definition

Domain and range of a function definitions of domain and range domain.

Domain and range math definition. Domain and range the domain of a function f x is the set of all values for which the function is defined and the range of the function is the set of all values that f takes. The domain of a function is all the possible input values for which the function is defined and the range is all possible output values. The domain and range of a function is all the possible values of the independent variable x for which y is defined.

The example below shows two different ways that a function can be represented. The domain of a function is the complete set of possible values of the independent variable. When finding the domain remember.

The range of a function is all the possible values of the dependent variable y. As a function table and as a set of coordinates. If you are still confused you might consider posting your question on our message board or reading another website s lesson on domain and range to get another point of view.

They may also have been called the input and output of the function.
