Question 88724

determine whether each relation is a function.. give the domain and range for each relation..
A.{(2,7)},(3,7),(5,7)}
Domain: {2,3,5}
Range: {7}
It is a function because each domain value has only one range value.
----------------------
B.{(1,10)(2,500),(13,pie)}
Domain: {1,2,13}
Range: {10,500,pi}
It is a function because each domain value has only one range value.
