Generally such bracketing denotes some form of grouping.

What does range mean in math functions.

Functions have been used in mathematics for a very long time and lots of different names and ways of writing functions have come about. Essentially the range tells us how spread apart a group of numbers is. 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. In mathematics brackets of various typographical forms such as parentheses square brackets braces and angle brackets are frequently used in mathematical notation.

The range of a simple linear function is almost always going to be all real numbers. Domain rarr function rarr range example. In evaluating an expression containing a bracketed sub expression the operators in the sub expression take precedence over those surrounding it. Essentially the range tells us how spread.

We have a special page on domain range and codomain if you want to know more. A mathematical concept is independent of the symbol chosen to represent it. Illustrated definition of range of a function. A graph of a typical line such as the one shown below will extend forever in either y.

The set of elements that get pointed to in y the actual values produced by the function is called the range. The range is the difference between the lowest and highest numbers in a data set.
