Ok first do you know what the domain is?

nope

Ok the domain is a list of all x-values, so here what are they.

I think I need to just youtube the session on this all together lol

ok this is easy just hang on

you can do this

{(1,2), (2,4), (3,6), (4,8)}
{(x,y), (x,y), (x,y), (x,y)}

does that make sense?

kind of

do I add the x's together and the y's together?

We are first finding the domain: all x-values:
{1,2,3,4}
Do you see how I got this?

yes those are all of the xs

wait, so that's it? there is no more work to it?

ok, what do you do once you've found the domain and the y values?

awesome now the range: all the y-values:
{2,4,6,8}

ok, so how do you do that? because for some reason I want to say it is a function...

We look at the domain, are any of those numbers the same?

the numbers in the domain are not the same but the ones in the range are, right?

I want to say 2 and 4 are but that's not right

oh lol im not smart. No, none of them are the same

thanks for putting up with me haha

lol no problem

every function is a relation, not every relation is a function
So this is a function AND a relation.
