It is a collection of the second values in the ordered pair (Set of all output (y) values). Example: In the relation, {(-2, 3), {4, 5), (6, -5), (-2, 3)}, The domain is {-2, 4, 6} and range is {-5, 3, 5}.

A relation is an expression that is not a function. A function is defined as only having one domain per range, meaning that when graphed, a function will have no two points on the same vertical line. If your expression is graphed and two points do appear on the same vertical line, it is a relation, not a function.
examples of number relation problems
you will know if it is Function because if you see unlike abscissa in an equation or ordered pair, and you will determine if it is a mere relation because the the equation or ordered pairs has the same abscissa. example of function: {(-1.5) (0,5) (1,5) (2,5)} you will see all the ordinates are the same but the abscissa are obviously unlike example of mere relation: {(3,2) (3,3) (3,4) (3,5)} you will see that the ordinates aren't the same but the abscissa are obviously the same. Try to graph it.!
If a vertical line intersects the graph at more than one point then it is not a function.
idont known the answer
In mathematics, a mere relation typically refers to a relationship between two or more entities without implying any specific structure or operation. It often describes a set of ordered pairs or a collection of elements that are related in some way, such as through equality, order, or equivalence. Unlike functions or operations that establish a more defined interaction, mere relations focus on the existence of a connection rather than the nature of that connection.
An relation is equivalent if and only if it is symmetric, reflexive and transitive. That is, if a ~ b and b ~a, if a ~ a, and if a ~ b, and b ~ c, then a ~ c.

In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.
