Here's a quite simple question. But well, I've dropped outta school for about 3.5 years, now that I got back to school, I'd require to learn some basics before heading to advanced stuffs.
I'm kinda confused on the increasing and decreasing of a function when the function has an absolute value( |a| )
Eg. f(x)=| x-2 |
how do I differentiate them? Or what shall I do?
