Get Intermediate Value Theorem Graph Background. Thus, applying the intermediate value theorem, we can say that the graph must cross at some point between (0, 2). The idea behind the intermediate value theorem is this:
Your teacher probably told you that you can draw the graph of a continuous function without lifting your pencil off the paper.
In mathematical analysis, the intermediate value theorem states that if f is a continuous function whose domain contains the interval a, b, then it takes on any given value between f(a) and f(b) at some point within the interval. Your teacher probably told you that you can draw the graph of a continuous function without lifting your pencil off the paper. The intermediate value theorem essentially makes a statement about a function that is continuous over some defined interval. Before talking about the intermediate value theorem, we need to fully understand the concept of continuity.
