Question
Is the relation shown below a function ? Explain.
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: { 4, 6 , 2 , 8 , 5 }
We have given the data in the tabular format
We will convert it into point format
As (3,4) , (4, 6) , (1, 2) , (5, 8) , (2, 5)
Domain:- { 3, 4, 1 , 5 , 2 }
Co- Domain:- { 4, 6 , 2 , 8 , 5 }
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.
