Define domain and range in mathematics.

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. Mathematical function means the association between two groups of variables. The range of a function is all the possible values of the dependent variable y.

As a function table and as a set of coordinates. Domain and range are terms that are applicable to mathematics especially in relation to the physical sciences consisting of functions.

All the values that go into a function. The domain and range of a function is all the possible values of the independent variable x for which y is defined. Domain rarr function rarr. However this coincidence is no longer true for a partial function.

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