Can two ordered pairs represent a function?
A function is a special type of relation . In formal mathematical language, a function is a relation for which: if (x1,y) and (x2,y) are both in the relation, then x1=x2 . This just says that in a function, you can’t have two ordered pairs with the same x -value but different y -values.
Is an ordered pair that represent a point?
An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.
How are ordered pairs represented?
Ordered pairs are often used to represent two variables. When we write (x, y) = (7, – 2), we mean x = 7 and y = – 2. The number which corresponds to the value of x is called the x-coordinate and the number which corresponds to the value of y is called the y-coordinate.
Does the ordered pairs represent a relation?
A relation is a set of ordered pairs. The set of all first components of the ordered pairs is called the domain of the relation and the set of all second components of the ordered pairs is called the range of the relation. Sometimes relations can be represented in a table.
Which ordered pair represents a point that is 3 points to the left and 2 points above point T?
In conclusion, the ordered pair representing 3 points to the left, and 2 points above point T is (0, 6).
What is the ordered pair for point A?
The ordered pair for point A is (3, 1). coordinate plane a space formed by two perpendicular number lines called axes. ordered pair a pair of numbers, or coordinates, (x, y) describing the location of a point on the coordinate plane.
Which ordered pair represents the origin?
The ordered pair for the origin is (0, 0). The x-coordinate tells how many units from the origin the point is on the x-axis. It is the first number in the ordered pair. The y-coordinate tells how many units from the origin the point is on the y-axis.
Which ordered pair is not a function?
In order for a relation to be a function, each x must correspond with only one y value. If an x value has more than one y-value associate with it — for example, in the relation {(4, 1), (4,2)}, the x-value of 4 has a y-value of 1 and 2, so this set of ordered pairs is not a function.
