For order pair
In the first block the value 9 maps to 4 So, (9,4)
The value 8 maps to 4 & 6 so, the pair is (8,4) & (8,6)
The value 4 maps to 5So, (4,6)
The order pairs are (9,4), (8,4) (8,6) & (4,5)
b) Domain are the set of input values
In this mapping the first block map to the second thus, the value at the first block is the initial valua and act as domain of the mapping
So, the Domain = {9,8,4}
c) Range is the set of all the possible outputs
In this mapping, the second block show the final values of the function, thus the second block act as a range of the mapping
So, the Range= {4,5,6}
d) The mapping doesnot represent the function as the mapping is not one-one
A function must staisfy one-one rulei.r for every value of domain thier exists only one value of range
Where in this mapping we have, the range 4 whose domain are 9 & 8 does they donot satisfy the one-one creteria hence they are not one-one and niether they are function
