#4Find the domain and range of the relation:{(8,2),(7,2),(6,2),(5,2)}{(8,-2),(7,-2),(6,-2),(5,-2)}. Then determine whether the relation is a function.

Domain = {} Separate your answers by commas.

Range = {} Separate your answers by commas.

Is the relation a function?

#5Alvin wants to know what his average paddling rate was for a canoe trip to a campsite. On the way there it took him 4 hours against a river current of 5 km/ hr. On the way back, the same distance took him 2 hours with the same 5 km/hr current. Letr= Alvin's average paddling rate.
