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. 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. Some people find it helpful to think of the domain and range as people in romantic relationships.

The output values are called the range. Domain rarr function rarr. In mathematics the domain or set of departure of a function is the set into which all of the input of the function is constrained to fall. Domain and range are prime factors that decide the applicability of mathematical functions.

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 the complete set of possible values of the independent variable. If each number in the domain is a person and each number in the range is a different person then a function is when all of the people in the domain have 1 and only 1 boyfriend girlfriend in the range. When finding the domain remember.

The domain is the set of all possible x values which will make the function work and will output real y values. Mathematical function means the association between two groups of variables. Compare the two relations on the below. X y and is alternatively denoted as.

It is the set x in the notation f. All the values that go into a function. However this coincidence is no longer true for a partial function. Since a function is defined on its entire domain its domain coincides with its domain of definition.

Illustrated definition of domain of a function. The example below shows two different ways that a function can be represented.
