JEE Math Practice Question
If c is a point at which Rolle's theorem holds for the function, f(x) = $${\log _e}\left( {{{{x^2} + \alpha } \over {7x}}} \right)$$ in the interval [3, 4], where a $$ \in $$ R, then ƒ''(c) is equal to
- A.$${1 \over {12}}$$
- B.$${{\sqrt 3 } \over 7}$$
- C.$$-{1 \over {12}}$$
- D.$$-{1 \over {24}}$$
