 The relation is not a function. 
Step-by-step explanation:
 By definition, a relation is a function if each input value has only one output value.
 Given the relation:
 (4,23)
 (3,-2)
 (-6,5)
 (4,6)
 The domain is the set of the x-coordinates of each ordered pair (You do not need to write 4 twice):
  {
{ }
}
 The range is the set of the y-coordinates of each ordered pair :
   {
{ }
}
 Since the input value 4 has two different output values (23 and 6), the relation is not a function.
