This lesson on limits is intended for students enrolled in AP Calculus AB or BC, Calculus Honors, or College Calculus.
What is a limit?
A limit of a function is the idea of looking at what happens to the y values of a function as x approaches particular values of x. In this discussion of limits, we are trying to find out what the y values tend to as x approaches some x value, say x=a, from either the left side or the right hand side of the graph.
In this unit, we explore what it means to find limits numerically.
