Those conditions satisfy the conditions of a function.
If every element of the first set is paired with exactly one element of the second set, it is called an injective (or one-to-one) function.An example of such a relation is below.Let f(x) and x be the set R (the set of all real numbers)f(x)= x3, clearly this maps every element of the first set, x, to one and only one element of the second set, f(x), even though every element of the second set is not mapped to.
If two numbers are given, the first one is usually the x-coordinate, the second, the y-coordinate.
The x coordinate in the second quadrant is negative while the y coordinate is positive.
The first coordinate always is called the "x" coordinate, because it goes on the "x" axis, while the second coordinate is always called the "y" coordinate because it always goes on the "y" axis.
Plot the two points, and you'll see that they are not the same point. Remember that the first number is for the first coordinate (usually to the right), and the second number is for the second coordinate (usually upwards).
Input is the first coordinate of an ordered pair in relationand Output is the second coordinate of an ordered pair in relation

This is most often called the "range" of the relation. * * * * * Though more often the first coordinate is the DOMAIN and the second coordinate is the RANGE.
A relation is any set of ordered pairs.A function is a relation in which each first element corresponds to exactly one second element
A relation is simply a collection of ordered pairs. That is, a relation is a pairing of an element from one set with an element from another set.A function is a special type of relation. In a function, each element from the first set (or domain) is paired with exactly one element from the second set (or range). That is, no domain element is used more than once.I will solve all your math problems. Check my profile for more info.
The first and second coordinate. X is the first coordinate and y is the second.
ordered pair
An example is: (5, 3) The first number is traditionally the x-coordinate, the second, the y-coordinate.
Second quadrant (II).
Not necessarily. x to sqrt(x) is a relation, but (apart from 0) the first component in each pair corresponds to two second components eg (4, -2) and (4, +2). The square root is, nevertheless, a relation, though it is not a function.
the ordinate
If two numbers are given, the first one is usually the x-coordinate, the second, the y-coordinate.
