Answer:

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.
