Domain =(3,4,6,5)
Range =(4,3,5,6)
It is a function

Explanation:

{(3,4),(4,3),(6,5),(5,6)}

Domain is the set of all x coordinate, so domain =(3,4,6,5)

Range is the set of all y coordinate, so range =(4,3,5,6)

From this, we can find out that every element in x has only one element in y.

So it is a Function.
