that's just a rough sketch @mathmate can you help? I'm not sure because of the gap

Domain 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
BloomLocke367
  • BloomLocke367
I know what domain and range are xp
BloomLocke367
  • BloomLocke367
I have a test tomorrow and I'm doing a review sheet lol. I have half of it done xp

  • BloomLocke367
yes I know something like that XD
BloomLocke367
  • BloomLocke367
but it's this particular graph that is bugging me
anonymous

I'll help someone then. Pm me if you need further help.

I know how to write interval notation and using inequalities lol XD

wouldn't it be [2,5)?
mathmate
  • mathmate
|dw:1441326076275:dw| Correction: \([2,5)\cup(9,\infty)\)
mathmate

So it's all clear how you would approach your particular problem?
BloomLocke367
  • BloomLocke367
yes I know...so would the domain be [-5,-1)U(3,+inf)?
mathmate
  • mathmate
The 3 in incorrect. The point lies on the y-axis, so it's zero. 3 is the y-coordinate.
BloomLocke367
  • BloomLocke367
ooopppppppppsss. 0, I just realized that. sorry my sister was talking to me and I really can't focus
mathmate
  • mathmate
Note: all points on the y-axis have x-value=0.
mathmate
  • mathmate
Good, so you're all set!
mathmate
  • mathmate
Can't do the range, because there is not enough information.
BloomLocke367
  • BloomLocke367
yes I know XD I'm just frustrated. now how would I write that particular domain using equalities?
BloomLocke367
  • BloomLocke367
INequalities*** ugh
mathmate
  • mathmate
In set notation, you could write: \(\{x | -5\le x < -1 \cup 0

  • anonymous
It is possible for the range is the parabola vertex is actually at 3
anonymous
  • anonymous
if the parabola*

phi
  • phi
the "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 \[ 2 \le x \lt 5\]
mathmate
  • mathmate
Do you mean (-3,2) ?
BloomLocke367
  • BloomLocke367
there 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
  • BloomLocke367
and yes I do omg I just can't get ANYTHING right today. I'm so sorry :(
phi
  • phi
you use U if you have to glue together "separated" domains
mathmate
  • mathmate
So what do you propose for the range?
mathmate
  • mathmate
It's similar to the domain, but look along the y-axis.
phi
  • phi
it looks like [0,2] U (3,inf)
BloomLocke367
  • BloomLocke367
that's what I was about to say @phi. I had to refresh
anonymous
  • anonymous
Is that an endpoint at the right side of the graph?
BloomLocke367
  • BloomLocke367
and no, it's an arrow
BloomLocke367
  • BloomLocke367
so set notation would be {\({y~|~0\le y \le 2 U 3
BloomLocke367
  • BloomLocke367
right? or am I wrong? idek. I'm about to give up and go to bed
phi
  • phi
yes
BloomLocke367
  • BloomLocke367
thank you.
