Essentially the range tells us how spread.
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.
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.
The range is the difference between the lowest and highest numbers in a data set.
Essentially the range tells us how spread apart a group of numbers is.
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.
Domain rarr function rarr range example.
In plain english this definition means.
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.
The domain of a function is the complete set of possible values of the independent variable.
Range can also mean all the output values of a function.
As a function table and as a set of coordinates.
The range of a function is all the possible values of the dependent variable y.
A graph of a typical line such as the one shown below will extend.
When functions are first introduced you will probably have some simplistic functions and relations to deal with usually being just sets of points.
The domain and range of a function is all the possible values of the independent variable x for which y is defined.
The range of a simple linear function is almost always going to be all real numbers.
Domain and range of a function definitions of domain and range domain.
The domain is the set of all possible x values which will make the function work and will output real y values.
