Continuity and DifferentiabilityHard
Question
The domain of the derivative of the functions f(x)
is
is Options
A.R -{0}
B.R -{1}
C.R -{-1}
D.R -{-1,1}
Solution
Given, f(x)
f(x) is discontinuous at x = - 1 and x = 1
∴ Domain of f′(x) ∈ R -{-1,1}
f(x) is discontinuous at x = - 1 and x = 1
∴ Domain of f′(x) ∈ R -{-1,1}
