So a continuous function, let's say that's my y-axis, that is my x-axis, a function is going to be continuous over some interval if it just doesn't have any jumps or discontinuities or gaps over that interval. So if it's connected, and it for sure has to be defined over that interval without any gaps. So for example, a continuous function could look something like this. This function, let me make that line a little bit thicker. So this function right over here is continuous. It is connected over this interval, the interval that we can see. Now examples of discontinuous functions over interval or non-continuous functions, well, they would have gaps of some kind.
