<PRE><B>Question 72728</B>
decide wether the relation is a function . If it is a function ,give the domain and the range   input     output
                  0         2
                  1         4
                  2         6
                  3         8
                     
--------------------
It is a function because each input value has just one output value
Domain: {0,1,2,3
Range: {2,4,6,8}
