Domain = 

 

Range = 

Answer 1

Dear Jessica,

 

     Look at all your coordinates points.  What is the set of "X's"?  This represents the domain.

 

  Domain=  (-2, -1,  1)   Don't write the -2 twice.

 

 

  The range relates to the set of all "y" values:

 

  Range= (0, 1, 4, 3)

 

     I hope this helps.

                                       Thank you,

                                       Susan
