B. The functions f(x) and g(x) be derivable in (a, b)
C. None of these
D. The derivation of g(x) be equal to 0
Explanation
Cauchy's Mean Value Theorem states that if two functions f(x) and g(x) are continuous on the closed interval [a, b] and differentiable on the open interval (a, b), and g'(x) ≠ 0 for any x in (a, b), then there exists a point c in (a, b) such that: (f'(c) / g'(c)) = (f(b) - f(a)) / (g(b) - g(a))
The necessary conditions for Cauchy's Mean Value Theorem are :
1. The functions f(x) and g(x) are continuous on [a, b]. 2. The functions f(x) and g(x) are differentiable on (a, b). 3. g'(x) ≠ 0 for any x in (a, b).
