Let Then at x=0 ,f(x) is
continous and diffrentiable
continous and non-diffrentiable
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
f(x) is continous
For diffrentiability
f(x) is continous , so now we will find
This limit exists , hence diffrentiable
Option 1)
continous and diffrentiable
Option 2)
continous and non-diffrentiable
Option 3)
neither continous nor diffrentiable
Option 4)
not continous but diffrentiable
