How to show that a solution exists to a functions using IVT

The video tutorial explains how to apply the Intermediate Value Theorem (IVT) to a continuous function defined on a closed interval. The function is evaluated at the endpoints to demonstrate that it takes on both negative and positive values, indicating that there must be a point where the function equals zero. The tutorial emphasizes the importance of continuity and closed intervals in applying the IVT and concludes by confirming the existence of a solution without specifying its exact location.
