Question

aine ( f(x)=|x-1| )
(1) ( fleft(x^{2}right)=left|x^{2}-1right| )
& ( (f(x))^{2}=frac{1}{4}|x-1|^{2} )
clealy ( f(x)^{2} eq(f(x))^{2} )
( u^{prime}: f(x+y)=|x+y-1| )
( f(x)+f(y)=|x-1|+|y-1| )
( S_{0} quad f(x+y) eq f(x)+f(y) )
in ( quad f(|x|)=|| x|-1| )
( f(f(x))=|x-1|=|x-1| )
( Rightarrow f(1 x)) eq(f(x)) )
( k(11) ) None ( delta 0, ) oright offion is ( (%) ) None

# Question 2 Let, f(x) = (x - 1, then Of(0) = (f(a)) ? www wwwwwwwwww wwwwwwww . Www ww www www f(x + y) = f(x) + f(y) 10.000 f(x) = f(x)} None

Solution
