Domain Vs Range

The domain is the set of all possible x values which will make the function work and will output real y values.

Domain vs range. The domain is all the x values and the range is all the y values. Domain is also defined as a set of all probable input values. 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.

To give the domain and the range i just list the values without duplication. The sun s angle over the horizon during the course of the day is a fitting example to depict domain and range. The range of a function is all the possible values of the dependent variable y.

The domain of a function is the complete set of possible values of the independent variable. But in fact they are very important in defining a function. 2 3 4 6 range.

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. There lies the second difference between domain and range. A mathematical function is a relationship between two sets of variables.

The example below shows two different ways that a function can be represented. Since we established that domain is the x values and range is all the f x values the domain will be represented in the x axis while the range in shown in the y axis. 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.

One is independent called domain and other is dependent called range. 3 1 3 6. The domain and range of a function is all the possible values of the independent variable x for which y is defined.
