An example of a function which is continuous everywhere but fails to be differentiable exactly at two points is ______.
उत्तर
An example of a function which is continuous everywhere but fails to be differentiable exactly at two points is |x| + |x – 1|.
Explanation:
|x| + |x – 1| is the function which is continuous everywhere but fails to be differentiable at x = 0 and x = 1.
We can have more such examples.
