What Is The Domain And Range Of: R=(5,-3), (7, -4), (6,-6), (5,9) And Is This A Function?
Answer:
First of all this set R is not a function because the domain is repeated twice in two coordinates sets. In other words, in (5, -3) and (5, 9) the domain is same, in consequence, it is not a function.
Moreover, domains are all the x-coordinates and ranges are all y-coordinates. Domains include 5, 7, 6 and ranges are -3, -4, -6 and 9.
Comment: Thanks for the help.
