Study Notes
Relations in Mathematics
- A relation in mathematics is a way of showing a connection or correspondence between two sets of values.
Examples of Relations
- An example of a relation is a set of ordered pairs, such as {(1, 2), (2, 3), (3, 4)}, where each element of one set corresponds to an element of the other set.
Types of Relations
One-to-One (Injective) Relation
- A one-to-one relation is characterized by each value of the independent variable being unique and associated with a unique value of the dependent variable.
Many-to-One Relation
- A many-to-one relation is characterized by two or more values of the independent variable being associated with the same value of the dependent variable.
One-to-Many Relation
- A one-to-many relation is characterized by some values of the independent variable being associated with more than one value of the dependent variable.
