The Total solution for NCERT class 6-12
Provethat the function f given by
isnotdifferentiable at x = 1.
The given function is
It isknown that a function f is differentiable at a point x = c inits domain if both
are finite and equal.
Tocheck the differentiability of the given function at x = 1,
considerthe left hand limit of f at x = 1
Sincethe left and right hand limits of f at x = 1are not equal, f is not differentiable at x =1
