How do I list the elements of the domain as a set and the elements of the range as a set? Also, is it a relation or a function?
{(1,2), (2,4), (3,6), (4,8)}

Best ResponseYou've already chosen the best response.0Ok first do you know what the domain is?

Best ResponseYou've already chosen the best response.0Ok the domain is a list of all xvalues, so here what are they.

Best ResponseYou've already chosen the best response.0{(1,2), (2,4), (3,6), (4,8)} {(x,y), (x,y), (x,y), (x,y)}

Best ResponseYou've already chosen the best response.0does that make sense?

Best ResponseYou've already chosen the best response.0do I add the x's together and the y's together?

Best ResponseYou've already chosen the best response.0so the first number in the coordinate is an xvalue and the second number is a yvalue. No we are not adding

Best ResponseYou've already chosen the best response.0We are first finding the domain: all xvalues: {1,2,3,4} Do you see how I got this?

Best ResponseYou've already chosen the best response.0wait, so that's it? there is no more work to it?

Best ResponseYou've already chosen the best response.0ok, what do you do once you've found the domain and the y values?

Best ResponseYou've already chosen the best response.0awesome now the range: all the yvalues: {2,4,6,8}

Best ResponseYou've already chosen the best response.0ok so so far we have: domain: {1,2,3,4,} range: {2,4,6,8} Now we need to determine whether it is a relation or a function

Best ResponseYou've already chosen the best response.0ok, so how do you do that? because for some reason I want to say it is a function...

Best ResponseYou've already chosen the best response.0A function is a set of ordered pairs in which each xelement has only ONE yelement associated with it. So none of the xvalues can be the same. So is this a function? Let's see if you can figure this out..

Best ResponseYou've already chosen the best response.0We look at the domain, are any of those numbers the same?

Best ResponseYou've already chosen the best response.0the numbers in the domain are not the same but the ones in the range are, right?

anonymous

Best ResponseYou've already chosen the best response.0ok, no that is not what we are looking for. to determine if it is a function, all we have to do is see if any of the xvalues are the same, here are the xvalues {1,2,3,4,} are any of them the same?

Best ResponseYou've already chosen the best response.0I want to say 2 and 4 are but that's not right

Best ResponseYou've already chosen the best response.0lol are any of the numbers physically the same? it is simple 1, 2, 3, 4 are any of those numbers the same number?

Best ResponseYou've already chosen the best response.0oh lol im not smart. No, none of them are the same

Best ResponseYou've already chosen the best response.0awesome so that means that this is a function: so this is what we have domain: {1,2,3,4} range: {2,4,6,8} relation or function: function

Best ResponseYou've already chosen the best response.0every function is a relation, not every relation is a function So this is a function AND a relation.
