In Exercise 5.8, we have to check whether the following conditions of Rolle’s Theorem is satisfied or not.

• Function is continuous in closed interval [a, b].
• Function is differentiable in open interval (a, b).
• For the function f(a) = f(b)

If all the three conditions of Rolle’s theorem is satisfied, then according to theorem there should be a value c of x in open interval (a, b) such that f'(c) = 0. Putting f'(c) = o, we can get the required value of c and verify the Rolle’s theorem for the given function. In Mean Value Theorem we have to check only two following conditions:

• Function is continuous in closed interval [a, b].
• Function is differentiable in open interval (a, b).

If both are true, then we can find a value c according to Mean Value Theorem (LMV), such that f'(c) = [f(b) – f(a)]/(b – a).
