Question
Identify domain and range of each function. Is it a function?
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: Therefore, the given data is a function.
We have given the data in the arrow diagram format
We will convert it into point format
As (5, 6) , (8, 11) , (10, 11) , (12, 11) , (14, 6)
Domain:- { 5 , 8 , 10 , 12, 14}
Range :- { 6, 11}
From the given data we can analyze that each element in the domain input set has exactly one output.
Therefore, the given data is a function.
Note: All functions are relations but all relations are not functions.
