# Intermediate value theorem - Limits

### Intermediate value theorem

There are times when we simply want to know if a solution, or root, with certain x and y coordinates exists within a given closed interval. In this section, we will learn about the intuition and application of the Intermediate Value Theorem (often abbreviated as IVT). Note that the Intermediate Value Theorem tells us neither the occurrence frequency of a particular solution, nor any information outside the given closed interval.
