Domain Meaning Functions

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.

Domain meaning functions. All the values that go into a function. Domain in math is defined as the set of all possible values that can be used as input values in a function. In the function machine metaphor the domain is the set of objects that the machine will accept as inputs.

In simple words we can define the domain of a function as the possible values of x that will make an equation true. However this coincidence is no longer true for a partial function. The domain of a function is the input numbers that when plugged into a function the result is defined.

When the function f x x2 is given the values x 1 2 3 then the domain is simply those values 1 2 3. X y and is alternatively denoted as. Since a function is defined on its entire domain its domain coincides with its domain of definition.

Domain of a function. The output values are called the range. 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.
