The domain of a function is the complete set of possible values of the independent variable.
Define range in math function.
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.
Domain and range of a function definitions of domain and range domain.
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.
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.
Essentially the range tells us how spread.
Essentially the range tells us how spread apart a group of numbers is.
The range is the difference between the lowest and highest numbers in a data set.
In 4 6 9 3 7 the lowest value is 3 and the highest is 9 so the range is 9 3 6.
Illustrated definition of range of a function.
The set of all output values of a function.
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.
When functions are first introduced you will probably have some simplistic functions and relations to deal with usually being just sets of points.
When finding the domain remember.
A graph of a typical line such as the one shown below will extend.
In plain english this definition means.
The domain and range of a function is all the possible values of the independent variable x for which y is defined.
