Best ResponseYou've already chosen the best response.0looks like a function to me

Best ResponseYou've already chosen the best response.3it's not a function because it fails the vertical line test

Best ResponseYou've already chosen the best response.3it's possible to pass a vertical line through more than one point dw:1442812678494:dw which is why it fails the vertical line test

Best ResponseYou've already chosen the best response.3as Mertsj said, `A relation is a set of ordered pairs.` so basically, a relation is anything with a bunch of points on an xy grid. In the case of the circle, it's a bunch of points plotted to form a circle. So yes @sloppycanada the circle graph is a relation

Best ResponseYou've already chosen the best response.0Does that make this https://gyazo.com/a34cdd8ec6f6b49f7e82aa5494c9f6e9 also a function?

Best ResponseYou've already chosen the best response.3that's a function because it is impossible to pass a vertical line through more than one point on the parabola So it passes the vertical line test
