What Does Range Mean In Math Functions

The set of all output values of a function.

What does range mean in math functions.

A mathematical concept is independent of the symbol chosen to represent it. The range is the set of all possible output values commonly the variable y or sometimes expressed as f x which result from using a particular function. The following is a list of mathematical symbols used in all branches of mathematics to express a formula or to represent a constant. For many of the symbols below the symbol is usually synonymous with its corresponding concept but in some situations a different convention may be used.

Functions have been used in mathematics for a very long time and lots of different names and ways of writing functions have come about. The range is the difference between the lowest and highest numbers in a data set. Essentially the range tells us how spread. Illustrated definition of range of a function.

Domain rarr function rarr range example. Essentially the range tells us how spread apart a group of numbers is. A graph of a typical line such as the one shown below will extend forever in either y. In evaluating an expression containing a bracketed sub expression the operators in the sub expression take precedence over those surrounding it.

The range of a simple linear function is almost always going to be all real numbers. We have a special page on domain range and codomain if you want to know more.
