Correct option
(a) h is continuous for all x
(c) h'(x) = 1, for all x > 1
(d) h is not differentiable at two values of x.
Explanation :
From the figure,
h(x) is continuous all x, but h(x) is not differentiable at two points x = 0 and x = L (due to sharp edges). Also
Hence, (a), (c) and (d) is correct answers.
