The example below shows two different ways that a function can be represented.
Define range in math function.
The domain is the set of all possible x values which will make the function work and will output real y values.
The set of all output values of a function.
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.
When functions are first introduced you will probably have some simplistic functions and relations to deal with usually being just sets of points.
Essentially the range tells us how spread.
Essentially the range tells us how spread apart a group of numbers is.
The range of a simple linear function is almost always going to be all real numbers.
Domain rarr function rarr range example.
Range can also mean all the output values of a function.
Illustrated definition of range 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.
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.
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.
A graph of a typical line such as the one shown below will extend.
Domain and range of a function definitions of domain and range domain.
In 4 6 9 3 7 the lowest value is 3 and the highest is 9 so the range is 9 3 6.
As a function table and as a set of coordinates.
In plain english this definition means.
