Domain Definition Math Example

All the values that go into a function.

Domain definition math example. In mathematics a function can be compared. The domain of a function is the set of all possible inputs for the function. It is quite common for the domain to be the set of all real numbers since many mathematical functions can accept any input.

Consider this box as a function f x x 2. Before getting into the topic of domain and range let s briefly describe what a function is. The range of a function is all the possible values of the dependent variable y.

The output values are called the range. As a function table and as a set of coordinates. Definition of domain domain of a relation is the set of all x coordinates of the ordered pairs of that relation.

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 and range of a function explanation examples in this article we will learn what a domain and range of a function mean and how to calculate the two quantities. The domain and range of a function is all the possible values of the independent variable x for which y is defined.

It is the set of all values for which a function is mathematically defined. The example below shows two different ways that a function can be represented. Domain function range.

A domain refers to all the values that go into a function. A simple mathematical function has a domain of all real numbers because there isn t a number that can be put into the function and not work. For example when we use the function notation f.
