The epsilon-delta definition of a limit is a difficult idea to master and these problems are designed to ease students into working with the concept.
This worksheet asks students to use a graph to find a value of delta that works for a given value of epsilon.
Then, the student is asked to graph a function and to use the graph to find an appropriate delta for a given epsilon.
This is not part of the AP Calculus AB/BC curriculum.
