Differences Concept Relations And Functions
Imagine a function as a machine, such as a calculating machine. It takes a number (input), then the function of processing the incoming number and its output is called output.
Each number (x) inserted is then connected to a single number as the output, but it can also be that some different input values give the same output value.
A. Relations
A = {2, 3, 6}
B = {2, 4, 6, 8, 10, 11}
The relation of set A to B is "factor of". The following is the relation form from A to B in the arrow diagram:
In relation from set A to B, set A is called Domain (result areas), while set B is called Kodomain (friend area) and all members that get pair from A are called Range (result areas)
B. Function
To name a function is used a single letter like, f, g, and other letters. Then f(x), which reads "f from x" denotes the value given by f to x. For example:
f (x) = x2 + 2, then f (3) = 32 + 2.

A. Relations
Definition of Relationship in Math
The relation of two sets A and B is the installation of A members with B members.Example of Relations
If :A = {2, 3, 6}
B = {2, 4, 6, 8, 10, 11}
The relation of set A to B is "factor of". The following is the relation form from A to B in the arrow diagram:
In relation from set A to B, set A is called Domain (result areas), while set B is called Kodomain (friend area) and all members that get pair from A are called Range (result areas)
B. Function
Definition of Function
F function f is a relation that connects each member of x in a set called a domain with a single value f(x) of a second set called a kodomain region.To name a function is used a single letter like, f, g, and other letters. Then f(x), which reads "f from x" denotes the value given by f to x. For example:
f (x) = x2 + 2, then f (3) = 32 + 2.
Example of Function
Which of the following relation is a function, if relation from A to B ?Answer :
- The first relation is a function, since every member of domain A is single relation to the member of codomain B.
- The second relation is not a function, because there is a member of domain A that is not single relation to member of the number of B's
- The third relation is not a function, because there is a member of domain A that is not related to the member of codomain B
Differences of Relations and Functions
So it can be concluded that a function is a relation, while a relation is not necessarily a function.Similarly this article.
