Question

Is the following relation forms a function ? Explain.
(49,13)(61,36)(10,27)(76,52)(23,52)

hintHint:

An ordered pair is represented as (INPUT, OUTPUT)
A function from set A to the set B is a relation which associates every element of a set A to unique element of set B.

The correct answer is: { 13, 36 , 27, 52 , 52}


    We have given the data
    As (49,13)(61,36)(10,27)(76,52)(23,52)
    Domain:-  {  49, 61, 10 , 76 , 23}
    Co- Domain:- { 13, 36 , 27, 52 , 52}
    From the given data we can analyse that each element in the domain input set has exactly one output.
    Therefore, the given data is a function.

    All functions are relations but all relations are not functions.
