    Question:

    An example of a function which is continuous everywhere but fails to be differentiable exactly at two points is ........  .

    Solution:        

    An example of a function which is continuous everywhere but fails to be differentiable exactly at two points is x + |x – 1|. The functions is continuous everywhere but fails to be differentiable exactly at two points x = 0 and x = 1.

    Question:

    If f is continuous on its domain D, then | f | is also continuous on D.

    Solution: True

    If a function is continuous on its domain, then the modulus of the function is also continuous in the same domain.

    Hence, | f |is also continuous on D.
