Solution - If F : [– 5, 5] → R is a Differentiable Function and If F ′(X) Does Not Vanish Anywhere, Then Prove that F (– 5) ≠ F (5). - Mean Value Theorem

Question

If f : [– 5, 5] → R is a differentiable function and if f ′(x) does not vanish anywhere, then prove that f (– 5) ≠ f (5).

Solution

It is given that f : [– 5, 5] → R is a differentiable function.

Since every differentiable function is a continuous function, we obtain

(a) f is continuous on [−5, 5].

(b) is differentiable on (−5, 5).

Therefore, by the Mean Value Theorem, there exists c ∈ (−5, 5) such that
