Using the 2nd Derivative Test for Extrema

This example demonstrates how to use the second derivative test to find extrema of a function using GeoGebra. Key math concepts involved include derivatives, second derivatives, and function extrema. Construction highlights involve using commands like Tangent to draw tangents, Max and Min to locate maximum and minimum points of the function, and objects like f', f'' to display the first and second derivative graphs. Suitable for high school mathematics education, helping students understand the application of second derivatives in function analysis.
