Best ResponseYou've already chosen the best response.0that's just a rough sketch @mathmate can you help? I'm not sure because of the gap

Best ResponseYou've already chosen the best response.0Domain is the interval of defined values in the x axis. (That means they are not undefined.) Range is the interval of defined values in the y axis

Best ResponseYou've already chosen the best response.0wouldn't it be [2,5)?

mathmate

Best ResponseYou've already chosen the best response.1dw:1441326076275:dw Correction: \([2,5)\cup(9,\infty)\)

Best ResponseYou've already chosen the best response.1So it's all clear how you would approach your particular problem?

BloomLocke367

Best ResponseYou've already chosen the best response.0yes I know...so would the domain be [5,1)U(3,+inf)?

mathmate

Best ResponseYou've already chosen the best response.1The 3 in incorrect. The point lies on the yaxis, so it's zero. 3 is the ycoordinate.

Best ResponseYou've already chosen the best response.0ooopppppppppsss. 0, I just realized that. sorry my sister was talking to me and I really can't focus

mathmate

Best ResponseYou've already chosen the best response.1Note: all points on the yaxis have xvalue=0.

Best ResponseYou've already chosen the best response.1Good, so you're all set!

Best ResponseYou've already chosen the best response.1Can't do the range, because there is not enough information.

Best ResponseYou've already chosen the best response.0yes I know XD I'm just frustrated. now how would I write that particular domain using equalities?

BloomLocke367

Best ResponseYou've already chosen the best response.0INequalities*** ugh

Best ResponseYou've already chosen the best response.1In set notation, you could write: \(\{x  5\le x < 1 \cup 0<x<\infty\}\)

phi

Best ResponseYou've already chosen the best response.0the "little end" of < is next to the smaller value and the "fat end" is next to the bigger number if you want to say [2,5) you write \[ 2 \le x \lt 5\]

Best ResponseYou've already chosen the best response.0there I fixed that issue. *takes a deep breath* and I know @phi I just didn't know know if U was included or not

BloomLocke367

Best ResponseYou've already chosen the best response.0and yes I do omg I just can't get ANYTHING right today. I'm so sorry :(

phi

Best ResponseYou've already chosen the best response.0you use U if you have to glue together "separated" domains

mathmate

Best ResponseYou've already chosen the best response.1So what do you propose for the range?

mathmate
 one year ago
Best ResponseYou've already chosen the best response.1It's similar to the domain, but look along the yaxis.

phi

Best ResponseYou've already chosen the best response.0it looks like [0,2] U (3,inf)

BloomLocke367

Best ResponseYou've already chosen the best response.0that's what I was about to say @phi. I had to refresh

Best ResponseYou've already chosen the best response.0Is that an endpoint at the right side of the graph?

BloomLocke367
 one year ago
Best ResponseYou've already chosen the best response.0and no, it's an arrow

BloomLocke367

Best ResponseYou've already chosen the best response.0so set notation would be {\({y~~0\le y \le 2 U 3<y<\inf}\)}

Best ResponseYou've already chosen the best response.0right? or am I wrong? idek. I'm about to give up and go to bed
