Question:

Suppose the functions f and g are continuous on [a, b] and differentiable on (a, b), where g(a) ≠ g(b). Then there is a point c in (a, b) at which

f(b) – f(a) _ f'(c) g(b) – 8(a) g'(c)'

This result is known as the Generalized (or Cauchy’s) Mean Value Theorem.

a. If g(x) = x, then show that the Generalized Mean Value Theorem reduces to the Mean Value Theorem.

b. Suppose f(x) = x2 - 1, g(x) = 4x + 2, and [a, b] = [0, 1]. Find a value of c satisfying the Generalized Mean Value Theorem.
