give a function which is continuous everywhere but not diffrentiable at exactly two points?

hsbhatt

|x²-3x+2|

hash_include

f(x) = 1 when x >=1
x when -1<x<1
-1 when x<= -1

ramkumar_november

f(x) = |x-1| + |x-2| is continuous everywhere

but not differentiable at x=1 and x=2 ........

i think that we can plenty of functions like this... putting mod sign over there.....

hii

just draw two triangles .. at the corner points it will not be differentiable ..

cheers
