Let be a function defined by . If K be the set of all points at which is not differentiable, then K has exactly:
two elements
three elements
five elements
one element
Properties of differentiable functions -
At every corner point f(x) is continuous but not differentiable.
ex: | x - a | is continuous but not differentiable at x = a for a > 0
- wherein
Condition for differentiability -
A function f(x) is said to be differentiable at if both exist and are equal otherwise non differentiable
-
