\[
\bigg||x-1|-5\bigg|-2 > 0
\]
OpenStudy (dls):
Correct,Next?

\[\sqrt{||x-1|-5|-2}\] better...
OpenStudy (anonymous):
Add 2 to both sides. Where areyou getting stuck?

I don't know how to deal with mod functions while solving for domain.
OpenStudy (anonymous):
where is the mod though?
OpenStudy (dls):
mod/absolute bars
OpenStudy (dls):
\[\Huge \sqrt{||x-1|-5|-2}\]
OpenStudy (anonymous):
so when you say 'mod' you mean the absolute value function?

Yes
OpenStudy (anonymous):
\[
|f(x)| < a\implies -a<f(x)<a\\
|f(x)| > a\implies a<f(x),\quad f(x)<-a\\
\]
OpenStudy (anonymous):
\[
\bigg||x-1|-5\bigg| >2 \implies |x-1|-5 < -2\quad\quad |x-1|-5 >2
\]
OpenStudy (anonymous):
The equations will keep splitting up and you'll have to keep track of all of them.
OpenStudy (dls):
okay,ill try and let you know!
