A real function is said to have the intermediate value property on an interval $[a, b]$ if, for each value $v$ between $\displaystyle f(a)$ and $f(b)$, there is some $c \in (a, b)$ such that $f(c) = v$. Thus, a function with the intermediate value property takes all intermediate values between any two points.

The simplest, and most important, examples of functions with this property are the continuous functions.
