Understanding Rolle's Theorem and Its Application

The video tutorial explains how to apply Rolle's Theorem to a given function on a closed interval. It begins by introducing the function and problem statement, followed by a review of Rolle's Theorem and its conditions. The tutorial then verifies that the function values at the endpoints are equal, ensuring the theorem's applicability. Next, it demonstrates finding the derivative using the product rule and solving for the value of C using the quadratic formula. The tutorial concludes by identifying the value of C where the derivative equals zero.
