Given the relation {(1, 4), (3, 6), (5, 4), (1, 8)}, find the domain and determine whether or not it is a function.

The domain of relation is {1,3,5}

It is not a function.

Step-by-step explanation:

Given the relation {(1, 4), (3, 6), (5, 4), (1, 8)}

We need to find the domain and determine if the given relation is function or not.

The domain of relation is {1,3,5}

But the given relation is not function because we have x=1 twice in the relation and the for the relation to be function the values of domain can't be repeated.

So, It is not a function.
