OpenStudy (anonymous):

at least look at the definition of a function and relation... can you do that?

OpenStudy (anonymous):

a function is a relation that assigns to each member of the domain exactly one member of the range

OpenStudy (anonymous):

a relation is any set of ordered pairs

OpenStudy (anonymous):

ok.. the domain is your x coordinates, and the range is all the y coordinates.

OpenStudy (anonymous):

look at all your x-coordinates... are they assigned to exactly one member of the range?

OpenStudy (anonymous):

idk for the answer I got 5

|dw:1338082376865:dw| They are all functions because they have a different why for each and every x. If you see in the chart the same x=2 is matched with a different value for why.
