Let , Then at x =0 f(x) is
continous but not diffrentiable
continous and diffrentiable both
neither continous nor diffrentiable
not continous but diffrentiable
As we have learned
Differentiability -
Let f(x) be a real valued function defined on an open interval (a, b) and (a, b).Then the function f(x) is said to be differentiable at if
-
For continuity
continous at x=0
For diffrentiabilty
is continous at x= 0 , so we will find
above limit exists so diffrentiable at x= 0
Option 1)
continous but not diffrentiable
Option 2)
continous and diffrentiable both
Option 3)
neither continous nor diffrentiable
Option 4)
not continous but diffrentiable
