Final answer:
The correct answer is the Mean Value Theorem, which relates the rate of change of a continuous and differentiable function to the average rate of change over an interval.
Step-by-step explanation:
If ab and f(a) f(b), then there is some value of c between a and b for which f'(c)=(f(b)-f(a))/(b-a). The correct answer to this question is C) Mean Value Theorem.
This theorem is essential in calculus and states that if a function is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there is at least one point c in the interval (a, b) where the instantaneous rate of change (derivative) of the function is equal to the average rate of change over the interval [a, b].
