HELP I DONT

@freckles

OpenStudy (mjdennis):

Is that \[\sqrt{11-x}\] ?

OpenStudy (mjdennis):

Do you know what a domain is? That is a good start. If you don't, try searching "domain and range and it will help.

OpenStudy (iwanttogotostanford):

@mjdennis yes a domain is a set of real numbers, and the x-axis

OpenStudy (iwanttogotostanford):

please @mjdennis

jhonyy9 (jhonyy9):

do you know what is the domain of squarroote - where is defined ?

OpenStudy (iwanttogotostanford):

@jhonyy9 no, i don't. I just need the whole process of how to solve this problem in steps please if you can.

jhonyy9 (jhonyy9):

so there are inside radical 11-x yes ? for defined domain of radical you need to know that this is defned on 11-x >0 so what mean that 11-x >0 or do you can solve it now ?

jhonyy9 (jhonyy9):

please collaborate

OpenStudy (iwanttogotostanford):

ok, i got x<-0+11 @jhonyy9

OpenStudy (iwanttogotostanford):

@jhonyy9

jhonyy9 (jhonyy9):

no

jhonyy9 (jhonyy9):

how you solve an inequalitie ?

OpenStudy (iwanttogotostanford):

I thought that was how...

OpenStudy (iwanttogotostanford):

how do i then>

jhonyy9 (jhonyy9):

11-x>0 add to both sides x and will get 11 > x yes ?

jhonyy9 (jhonyy9):

ok. ?

OpenStudy (iwanttogotostanford):

and then what? I don't know what to do after that.... @jhonyy9

OpenStudy (iwanttogotostanford):

@jhonyy9

OpenStudy (iwanttogotostanford):

here are my answer choices btw: All real numbers except 11 x > 11 All real numbers x ≤ 11

OpenStudy (bunbunbun):

basically means that ur answer should be: domain is 11>x it may also be x<= 11

OpenStudy (bunbunbun):

so it is the last answer! c: x ≤ 11 because x ≤ 11 is the same as 11>x and square root 0 is 0 so domain can include 11

thanks you!!!
