When you're looking for something, you would like to know where it is. In math, we can tell you exactly where a place is by using what is called ordered pairs. Help us use ordered pairs to find bones in this lesson. Checkers Pretend you are playing checkers with a person who can'...
One more time:A relation is just a set of ordered pairs. There isabsolutely nothing specialat all about the numbers that are in a relation. In other words, any bunch of numbers is a relation so longas these numbers come in pairs. firstnumbers of theordered pairs. In other words, the ...
Ordered Pair: Definition An ordered pair is a pair of elements or numbers written in a specific and fixed order. On a Cartesian plane, an ordered pair (x, y) is defined as thecoordinatesof a point such that “x” is the x-coordinate and “y” is the y-coordinate. ...

We often call a function "f(x)" when in fact the function is really "f"Ordered PairsAnd here is another way to think about functions:Write the input and output of a function as an "ordered pair", such as (4,16).They are called ordered pairs because the input always comes first, ...
Definition of Origin in Math In mathematics, especially in the field of coordinate geometry; origin is said to be the initial point or the starting point from where we begin our calculations or measurements. On a ruler, the 0 is from where we start our measurements; hence it is said to ...

Order analysis is also very powerful in combination with other types of analysis like torsional analysis, combustion, or power analysis. Order tracking is a true “electrocardiogram” for machines. Sketch of an Order analysis configuration, with analog and angle sensors, mounted on rotating machinery...
In the following pair, which number is greater? 1.0275 or 1.029 Can the ordered pair of numbers (1,2) (3,2) (7,5) be called a function? What are both ordered pairs of integers (x,y) that satisfy (1 + x + y)^2 = 1^2 + x^2 + y^2 ...
Okay, this one's a trick question. Each element of the range that has a paired value from the domain. But what about that16in the domain? Itisin the domain, but it has no range element that corresponds to it; there is no ordered pair with16as its abscissa. This won't work! So ...
