Question

Is the relation shown below a function ? Explain
(4,16)(5,25)(3,9)(6,36)(2,4)(1,1)

Hint:

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: { 16, 25 , 9 , 36 , 4 , 1}


    We have given the data as
    (4,16)(5,25)(3,9)(6,36)(2,4)(1,1)
    Domain:-  {  4, 5 , 3 , 6 , 2 , 1  }
    Co- Domain:- { 16, 25 , 9 , 36 , 4 , 1}
    From the given data we can analyse that each element in the domain input set has exactly one output.
    The members in the domain set has its square as a output in the co-domain set
    Therefore, the given data is a function.

    Note: All functions are relations but all relations are not functions.
