Definition Of Range In Math Functions

Functions were originally the idealization of how a varying quantity depends on another quantity. Standard mathematical notation allows a formal definition of range. It is often assumed to be the set of all real numbers and y there exists an x in the domain of f such that y f x is called the image of f.

The range of a function is the set of outputs the function achieves when it is applied to its whole set of outputs. The domain of a function is the complete set of possible values of the independent variable. 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. In plain english this definition means.

The domain is the set of all possible x values which will make the function work and will output real y values. The image of f x 2 is the set of all. Illustrated definition of range of a function.
