A change of sign key is a technique used in numerical methods to identify the roots of a function. It relies on the Intermediate Value Theorem, which states that if a continuous function changes sign over an interval, there must be at least one root within that interval. By evaluating the function at specific points, one can locate intervals where the function transitions from positive to negative or vice versa, indicating the presence of a root. This method is particularly useful for approximating roots in iterative algorithms like the bisection method.
