Interactive Left and Right Hand Limits

This activity is designed to help you determine the right and left hand limits at a point. It will help us see whether or not the limit at the point exists. How do you think knowing the left and right hand limits helps us determine the overall limit at a point? You may change f(x) by double clicking on f(x) in the margin under "Free Objects." Be sure to leave "f(x) =" alone and only change the right side. You may have to adjust the axes depending on the function. If you adjust the axes, you can move the text around the page to fit it on your screen.
