B find the domain and range of ordered pairs represented on the graph. There are no restrictions as the ordered pairs are simply listed.

This corresponds to the set of y values when we describe a function as a set of ordered pairs x y. This mapping or set of ordered pairs is a function because the points do not make a vertical line.

They may also have been called the input and output of the function. X y the range of f is the set of y values such that y f x for some x in x. Determine the domain and range of each graph pictured below.

All real y 0. The range is the set of the second coordinates of the ordered pairs. A function is a set of ordered pairs such as 0 1 5 22 11 9. In mathematics what distinguishes a function from a relation is that each x value in a function has one and only one y value.

This is called the vertical line test of a function. The output value is the second coordinate in an ordered pair. The set of all first coordinates of the ordered pairs is the domain of the relation or function. Like a relation a function has a domain and range made up of the x and y values of ordered pairs.

Domain and range the domain of a function f x is the set of all values for which the function is defined and the range of the function is the set of all values that f takes. In grammar school you probably called the domain the replacement set and the range the solution set. If any relation from set a to set b is r then range of relation r is defined as collection of.
