To state: the domain and range of relation. Then determine whether relation is a function, if it is determine if it is one-to-one, onto, both , or neither.
Answer to Problem 61STP
Domain :
Range :
The relation is not a function.
Explanation of Solution
Given information:
Formula used:
A function is a relation in which each element of the domain is paired with exactly one element in the range.
One-to −One function: Each element of the domain pairs exactly one unique element of the range.
Onto function: Each element of the range corresponds to an element of the domain.
Calculation:
According to the question ,
Domain :
Range :
The relation is not a function because element -4 of domain has been mapped to two elements of the range 3 and 9.
Hence , the relation is not a function.
