The following is the answer.
The domain.
Ordered pairs are used for many things. Anytime you graph a point on a cartesian coordinate system, you have an ordered pair. In fact, all of R^2 is made up of ordered pairs. When you put a value in a function and get one out, you have an ordered pair
An ordered pair is a list of two numbers, in which the order matters. For example, (5, 2) is an ordered pair; this pair is not the same as (2, 5). For comparison, for the numbers in a set the order does not matter.
The domain is the set of the first number of each ordered pair and the range is the set of the second number.
A set ordered pair is...called a set ordered pair
A ordered pair is one of many ways in which a function may be defined. The function maps the element in the first position of an ordered pair to the second element in that pair.
Evaluate the function at the first number in the pair. If the answer is not equal to the second value, then the ordered pair cannot be in the function.
If a set of ordered pairs is not a relation, the set can still be a function.
(1,2)
The abscissa
They are the set of abscissae.
You can easily test any ordered pair that someone may offer you, to determinewhether the pair is part of the graph of the function [ y = 3 - x ].Simply check to see whether the sum of the two members of the ordered pair is 3.If yes, and only if yes, then the pair is part of the graph of the function.
No
The set of all possible second coordinates of the ordered pair ina function is called the image of the function and is often denoted im(f). In other words, the image is all possible outputs of a function
The following is the answer.
A relation is when the domain in the ordered pair (x) is different from the domain in all other ordered pairs. The range (y) can be the same and it still be a function.
