Quadratic Functions - Vertex

This example demonstrates the graph of a quadratic function and its vertex. A quadratic function is a fundamental concept in algebra, and its graph is a parabola. By adjusting parameters h and k, the position of the vertex can be observed. The example uses the function command f(x) = a(x-h)^2 + k in GeoGebra, along with text objects to label key points. Suitable for students at the middle school level and above to learn about the properties and transformations of quadratic functions.
