A journey along the graph of a function - Increasing and Decreasing Functions

Click the Start button to start the journey of the Tortoise along the graph of the function. When the Tortoise stops, click on him to start the next section of the trip. Irina Boyadzhiev, Created with GeoGebra

This applet can be used for illustration of “increasing” and “decreasing” intervals for a function. The students with some knowledge of calculus can look at the graph of the derivative and how it relates to the intervals of increasing/decreasing.

Increasing and Decreasing Functions

Use the check boxes to show/hide the objects and use the slider to move the points.
This is a Java Applet created using GeoGebra from www.geogebra.org - it looks like you don't have Java installed, please go to www.java.com In an increasing function, the value of y-increases as the value of x-increases. On the other hand, in a decreasing function, the value of y-decreases as the value of x-increases.
