for drawin that graph first draw y=5-x [shud be simple] ...

then u rep x by |x| ..

in the process u have to make graph symmetric abt y axiss cuz x or -x it dosnt matter !!!!!!!!

then takin modulus of the entire thing ... where ever the graph goes to negative y ...bring it up .....

then drawin 7 ^ blah blah shud be simple
