Question

Is the set {(1,4),(2,5),(3,5),(4,6),(5,7)} a function?

Answer 1

Answer:

Yes , because every element of domain has only one image.

Step-by-step explanation:

1 is related only 4 and not with any other element of domain I.e., we have only (1,4) and not (1,3) , (1,4) , or any other duplet where 1 is related with any second element..

Same is the case with 2,3,4, and 5.

So, this relation is an example of a function.
