The output values are called the range.

Domain of a function math definition. Representing a function. X y and is alternatively denoted as. Illustrated definition of domain of a function.

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. The domain of a function is the complete set of possible values of the independent variable. In other words it is the set of x values that you can put into any given equation.

Another way to put it is that the domain of a function is the set of all possible values that x can be equal to that will make a valid equation. Functions whose domain are the nonnegative integers known as sequences are often defined by recurrence relations. The domain of a function is the set of numbers that can go into a given function.

If you want to know how to find the domain of a function in a variety of situations just follow these steps. Since a function is defined on its entire domain its domain coincides with its domain of definition. Domain definition the domain of a function is the set of its possible inputs i e the set of input values where for which the function is defined.

The factorial function on the nonnegative integers is a basic example as it can be defined by the recurrence relation. In the function machine metaphor the domain is the set of objects that the machine will accept as inputs. Domain rarr function rarr.

In plain english this definition means. 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. There are only two instances in which an equation.
