ANSWER

  • For the first relation the ordered pairs are:(-2,-5),(-2,3),(1,-1),(2,3),(6,2)
  • The domain refers to set of x-values of the relation.
  • Domain: {-2,1,2,6}
  • Range {-5,-1,2,3}
  • Range refers to the set of all y-values of the relation.
  • This relation is not a function because -2 alone has two different y-coordinates which are -5 and 3.
  • For the second relation, the ordered pairs are: (-5,-4), (-3,-2), (-2,1),(0,2),(2,1),(3,0)
  • Domain: {-5,-3,-2,1,0,2,3}
  • Range:{-4,-2,0,1,2}
  • This relation is a function because no x-value maps on to more than one y-value.
  • For a mapping diagram, the set of all the x-coordinates form the domain and the corresponding y-coordinates are in the Range
  • See attachment for the mapping diagram s.
