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.
A relation is any set of ordered pairs.A function is a relation in which each first element corresponds to exactly one second element
Is it true that in a relation for each element of the domain there is only one corresponding element in the range

A set of ordered pairs that assign to each x-value exactly one y-value is called a function.

Employment And Ordered Arrangement Of Forces In Relation To Each Ther
The INVERSE of any relation is obtained by switching the coordinates in each ordered pair.
Tactics
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.
Range
A relation is a set of ordered pairs.A function is a relation such that for each element there is one and only one second element.Example:{(1, 2), (4, 3), (6, 1), (5, 2)}This is a function because every ordered pair has a different first element.Example:{(1, 2), (5, 6), (7, 2), (1, 3)}This is a relation but not a function because when the first element is 1, the second element can be either 2 or 3.
The first number in each pair must be unique.
It is the coordinate or Cartesian plane.
The domain.
