If f x min x x 1 2 x 1 then f x is ........

If f(x) = min {|x|, |x-1|, 2-|x-1|} , then f(x) is

Discontinuous at exactly three points

Maximum value of f(x) is 2

c) f(x) is non-differentiable at x= - 1/2, 0. 1/2. 1, 2, 5/2

f(x) is non-differentiable at $x=-\frac{1}{2},0,1,2,\frac{5}{2}$

f(x) is non-differentiable at $x=-\frac{1}{2},0,1,2,\frac{5}{2}$ ?
