Definition Of Range In Math Functions

Range can also mean all the output values of a function.

Definition of range in math functions. The image of f x x 2 is the set of all non negative real numbers if the domain of the function is the set of all real numbers. 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 range is 1 4 9 domain range and codomain. Range of a function mathematics the set of values of the dependent variable for which a function is defined.

Range of a function. In plain english the definition means. In the function machine metaphor the range is the set of objects that actually come out of the machine when you feed it all the inputs. The range of a function is the set of outputs the function achieves when it is applied to its whole set of outputs.

The set of all output values of a function. The difference between the lowest and highest values. In mathematics the range of a function refers to either the codomain or the image of the function depending upon usage. For example when we use the function notation f.

The range is the resulting y values we get after substituting all the possible x values. The range of a function is the complete set of all possible resulting values of the dependent variable y usually after we have substituted the domain. As a function table and as a set of coordinates. In 4 6 9 3 7 the lowest value is 3 and the highest is 9 so the range is 9 3 6.

The codomain is a set containing the function s output whereas the image is only the part of the codomain where the elements are outputs of the function. The domain and range of a function is all the possible values of the independent variable x for which y is defined.
