Domain Math Term

Domain of a function.

Domain math term. The term domain is most commonly used to describe the set of values for which a function map transformation etc is defined. The domain is the set of all possible x values which will make the function work and will output real y values. Since a function is defined on its entire domain its domain coincides with its domain of definition.

As a function table and as a set of coordinates. The example below shows two different ways that a function can be represented. When the function f x x2 is given the values x 1 2 3 then the domain is simply those values 1 2 3 domain range and codomain.

Domain the set of values of the independent variable s for which a function or relation is defined. X y and is alternatively denoted as. Typically this is the set of x values that give rise to real y values.

In plain english this definition means. An example in which the domain is not all real numbers is when a function results in an undefined. The term domain has at least three different meanings in mathematics.

For example a function that is defined for real values has domain and is sometimes said to be a function over the reals. It is the set of all values for which a function is mathematically defined. Domain in math is defined as the set of all possible values that can be used as input values in a function.

The domain of a function is the complete set of possible values of the independent variable. Definition of domain domain. The range of a function is all the possible values of the dependent variable y.
