Best ResponseYou've already chosen the best response.0dw:1440792391540:dw I'm not sure if it's \(6<x<3\) or \(6\le x \le 3\), but I'm PRETTY sure it's the first one.

Best ResponseYou've already chosen the best response.0I know I didn't include the points, but that's what they are, lol

Best ResponseYou've already chosen the best response.1the open circles means the relation doesn't exist there

Best ResponseYou've already chosen the best response.1your relation is not defined anywhere else for x=6 or x=3 so you definitely will not include x=6 or x=3

Best ResponseYou've already chosen the best response.0So the first inequality was correct?

Best ResponseYou've already chosen the best response.1yes you don't want to include x=6 or x=3 and your second inequality does that that is what the little horizontal lines under the inequalities mean less than or equal to

Best ResponseYou've already chosen the best response.1yea the 1st inequality is correct cause the values 6 and 3 are omitted in the graph :)

Best ResponseYou've already chosen the best response.0Yes, I know that part @freckles. haha

Best ResponseYou've already chosen the best response.1oh then I guess I wasn't sure why you were asking why not to include the equality part

Best ResponseYou've already chosen the best response.0Idek why I was uncertain. I think it's because it was a circle and it was on both sides, but I don't know XD thanks thought :)

Best ResponseYou've already chosen the best response.1dw:1440793380136:dw if it was this then you say: \[6 < x \le 3 \]

Best ResponseYou've already chosen the best response.1dw:1440793415292:dw or if it was this then you would say: \[6 \le x \le 3 \]

Best ResponseYou've already chosen the best response.1but hey do we know where is the center of the circle? is it situated at the origin?

Best ResponseYou've already chosen the best response.1and the one more possibility just for fun: dw:1440793456096:dw then you would say: \[3 \le x < 6 \]

Best ResponseYou've already chosen the best response.0Yes, I know what the closed and open circles mean lol XD and no, it's not. I just did a quick sketch of a circle. I have it in front of me on an actual graph with points. I understand now. Thanks

Best ResponseYou've already chosen the best response.1@imqwerty i think it is not a circle because the midpoint of x=6 and x=3 is not 0

Best ResponseYou've already chosen the best response.1not a circle centered at (0,0)*

Best ResponseYou've already chosen the best response.1i asked the most stupid question :'( :P

Best ResponseYou've already chosen the best response.0it is a circle. the center is at (1,1). I just didn't draw it that way

Best ResponseYou've already chosen the best response.0dw:1440793616192:dw those bottom points all have the same yvalues, I just didn't bother showing it. XD But one is open and one is closed so would the inequality be the less than or equal to symbol...since it still touches that point in other areas?

BloomLocke367

Best ResponseYou've already chosen the best response.0well, not really that point, but that yvalue

Best ResponseYou've already chosen the best response.1so are you looking at range then

Best ResponseYou've already chosen the best response.1dw:1440793821415:dw well a is included

Best ResponseYou've already chosen the best response.1because that one dot is filled at y=a

freckles

Best ResponseYou've already chosen the best response.1so the range would be [a,b]

Best ResponseYou've already chosen the best response.1or equivalently an inequality form a<=y<=b

Best ResponseYou've already chosen the best response.0So I was right. Thanks! I just wanted to make sure I wasn't wrong. xp
