Question

Do you find the topic relation to be a difficult one? If so the following information has been provided to help you.

A relation can be represented:

• using an algebraic expression

• by use of a relation/mapping/arrow diagram
• as a graph

• as a set of ordered pairs

{(1,3),(2,5),(3,7).......}

There are 4 types of relations:

1. one to one mapping.(1-1)
2. many to one mapping. (M-1)
3. one to many mapping. (1-M)
4. many to many mapping. (M-M)

A function is a relation in which one or more numbers in the domain is mapped onto only one and only one number in the range. Thus a function maybe:

• a one to one mapping or
• a many to one mapping
