Like...
(- infinity sign, infinity sign)
(- infinity sign, -1]
(-3,0]
[-1,8)

i am tired as heck after having to type that lol

Please medal and fan if this helps you

note when one of the numbers infinity or - infinity it's always a '(' or ')'

Yep

Um what?

I have no clue what dot things your talking about. I dont have a book to look at

if you read everything outloud to yourself it will make sense

My examples show ( ) and [ ]

That is all i can do to help. i hope you understand

I rather no draw a number line for every problem I do.. Is there a easier way

not *

It doesnt matter if I read it allowed or not I dont understand anything you said.

one of your examples is (-3,0]
that means 'greater than -3 and less than and including 0'.

Okay I get that.. And my examples were just to show someone what Im talking about

so are you happy with the answers given?

ok
so what does
[ , INf sign) mean

? Like [1, infinity sign) ??

yes

Okay.. [ means less than and including 1.. ) means greater than infinity

No It means greater than and including 1 and up to infinity

I dont get it then

- in other words all numbers from and including 1 and going on infinaiely

that the square bracket [

means 'included'

I dont care about that. I just want to know how to know where to put () and []

I assumed there was some trick people knew that helped them figure it out quick.

when you have square it includes the end values

Yes..

yes
the domain for that function is
(-3,0]

the x -3 has the emplty circle but x = 0 has filled one

Yeah.. But how do you know where to put the 9 and ] at??

( ] **

well ( when the number is not included - so it comes before the -3

|dw:1441818059986:dw|

Um okay I think I understand that..

So the range would be (5,-4] ??

the lowest value of y comes first in the range
this is -5
and the highest is 5

Sorry lowest is -4

So [-4,5)

yes

-4 is included but 5 is not

Okay I think I understand

good

Thank you.
