Domain and range definition algebra. 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. 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. Values in the domain map onto values in the range. Change the domain and we have a different function.
Domain rarr function rarr. The domain is the set of all possible x values which will make the function work and will output real y values. In grammar school you probably called the domain the replacement set and the range the solution set. The horizontal and vertical line test can help determine the type of relation between the domain and range.
The range is the set of possible output values which are shown on the y axis. Domain and range of a function definitions of domain and range domain. Keep in mind. They may also have been called the input and output of the function.
The domain is all the x values and the range is all the y values to give the domain and the range i just list the values without duplication. The above list of points being a relationship between certain x s and certain y s is a relation. When finding the domain remember. But we can define the domain.

All the values that go into a function. The domain of a function is the complete set of possible values of the independent variable.
In its simplest form the domain is all the values that go into a function and the range is all the values that come out. Another way to identify the domain and range of functions is by using graphs. A simple function like f x. The output values are called the range.
Some people find it helpful to think of the domain and range as people in romantic relationships. The range of a function is all the possible values of the dependent variable y. Domain range and codomain. 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. 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.
