Example: take the closed interval [0,1] and open interval (1/3, 2/3). let k = [0,1] (1/3,2/3). for x e [0,1] define f (x) = d(x,k) where d (x, k) = inf {}x - yl

Example: Take the closed interval [0,1] and open interval (1/3, 2/3). Let K = [0,1] (1/3,2/3). For x E [0,1] define f (x) = d(x,K) where d (x, K) = inf {}x - yl ye K}. Then (CSIR NET MA June 2016) R is differentiable at all point of (0,1) R is not differentiable at 1/2 0 if xE0 f: [ 0,1] (1) (2) f:[0,1] > R is not differentiable at 1/3 and 2/3 (3) f: [0,1] (4) f: [0,1] Ris not continuous Solution :(2,3) f[O,1] R is defined as if xe3 2 f(x)= 1 21 2-x if xE3 0 if xe and as LHD and RHD are Clearly f is continuous on [0,1] but not differentiable at different at these points AAn 7CeRAOCDn
