Question
If f(x) = 
be a real - valued function then
be a real - valued function thenOptions
A.f(x) is continuous, but f ′(0) does not exist
B.f(x) is differentiable at x = 0
C.f(x) is not continous at x = 0
D.f(x) is not differentiable at x = 0
Solution
f(0) = 0
f(x) = 
= 0
f(x) is conti. at x = 0
LHD =
= 1
