they are the first set of paired elements
A relation is any set of ordered pairs.A function is a relation in which each first element corresponds to exactly one second element
domain
its the x coordinate (first number) It is the set of values that the x coordinate can take.
They are the set of abscissae.
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 set of ordered pairs is a relation. Or Just simply "Coordinates"
Usually the set of x values.
The domain is all the first coordinates in a relation. A relation is two ordered pairs.
In the ordered pair (a, b), the object a is called the first entry, and the object b the second entry of the pair. Alternatively, the objects are called the first and second coordinates, or the left and right projections of the ordered pair.
Input is the first coordinate of an ordered pair in relationand Output is the second coordinate of an ordered pair in relation

domain
It is called the first coordinate
It is the abscissa.
It is called the ORDINATE. The first is called the abscissa.
Cartesian coordinates. Also, the abscissa and the ordinate.
All functions are relations but all relations are not functions.
