Discontinuous Function: A discontinuous function has one or more breaks, holes, or jumps in its graph. It cannot be drawn without lifting the pen from the paper.
This theorem states that if a continuous function takes on two different values at two points within an interval, then it must also take on every value between those two points within that interval.
The limit of a function represents what value it approaches as the input gets arbitrarily close to a certain point. It helps determine behavior near points of discontinuity and infinity.
