Define Range In Math Function

These won t be terribly useful or interesting functions and relations but your text wants you to get the idea of what the domain and range of a function are.

Define range in math function. The domain of a function is the complete set of possible values of the independent variable. The range of a function is all the possible values of the dependent variable y. Range can also mean all the output values of a function. The range is the difference between the lowest and highest numbers in a data set.

The domain and range of a function is all the possible values of the independent variable x for which y is defined. A graph of a typical line such as the one shown below will extend. The range is the set of all possible output values commonly the variable y or sometimes expressed as f x which result from using a particular function. Essentially the range tells us how spread apart a group of numbers is.

When functions are first introduced you will probably have some simplistic functions and relations to deal with usually being just sets of points. Domain and range of a function definitions of domain and range domain. The range of a simple linear function is almost always going to be all real numbers. The example below shows two different ways that a function can be represented.

The domain is the set of all possible x values which will make the function work and will output real y values. As a function table and as a set of coordinates. The set of all output values of a function. By definition the range is the set of all the outputs of a function so to find the range we simply list the outputs 6 4 2 0 2 4 6.

Illustrated definition of range of a function. When finding the domain remember. In 4 6 9 3 7 the lowest value is 3 and the highest is 9 so the range is 9 3 6.
