A (a)   is an association or pairing of some kind between two sets of quantities or information.

A (a)   is a relation where one element from the first set is associated with more than one element in the second set.

A __________ relation is a relation where each element in the first set is paired with a unique element in the second set.

A __________ is a relation where the elements in the first set are paired with one element in the second set.

5. __________ is the set of all first elements in a relation.

6. __________ is the set of all the second elements in a relation.

A __________ is a well defined relation where no two ordered pairs have the same first element.

A __________ represents a function if no two ordered pairs have the same first elements or component.

The __________ is the set of all points on the coordinate plane corresponding to the ordered pairs in the function. If the domain and range of the function is the set of real numbers, the points are connected hence producing a continuous graph. If the domain and the range are not real numbers, then the graph will be discrete, that is, the graph is a series of unconnected points.

The __________ shows whether a graph represents a function or not.
