Determine whether each relation is a function. {(0,2), (4,2), (3,2), (5,1), (6,2)}

Do you know the difference between relation and function?

nope i never payed attention in math

Why?

it boring

then why are you doing it?

idk

Let me know when you know that :)

Are u going to help me not

Check out that link

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

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

a relation is any set of ordered pairs

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

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

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.
