In previous modules you used the graph of a function to investigate its derivative. In this module you will use the derivative to find properties of the original function. You will also investigate what the second derivative says about a function.

Lesson Index:

9.1 - What the First Derivative Says About the Function

9.2 - What the Second Derivative Says About the Function

After completing this module, you should be able to do the following:

• Use the Derivative and Tangent features in the Graph Math menu
• Describe what the first derivative says about a function
• Use the tanimate program to illustrate the relationships between a function and its first and second derivatives
• Use the Inflection feature in the Graph Math menu
• Use the Derivative key to find second derivatives
• Describe what the second derivative says about a function
