Continuity and DifferentiabilityHard
Question
Select the correct statements -
Options
A.The function f defined by f(x) = 
is neither differentiable nor continuous at x = 1.
is neither differentiable nor continuous at x = 1.B.The function f(x) = x2 | x | is twice differentiable at x = 0
C.If f is continuous at x = 5 and f(5) = 2 then 
f(4x2-11) exists.
f(4x2-11) exists.D.If (f(x)+g(x)) = 2 and (f(x) - g(x)) = 1 then f(x). g(x) may not exist.
(f(x)+g(x)) = 2 and (f(x) - g(x)) = 1 then f(x). g(x) may not exist.More Continuity and Differentiability Questions
