Question
Is the relation shown in the table 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: { 15, 20 , 50 , 80 , 100 }
We have given the data in the tabular format
As (0,15) , (5, 20) , (10, 50) , (15, 80) , (20, 100), (25 ,100)
Domain:- { 0, 5, 10, 15, 20, 25 }
Co- Domain:- { 15, 20 , 50 , 80 , 100 }
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.
