Quadratic Function (Stage 1)

This example demonstrates the basic graph and properties of quadratic functions. Key mathematical concepts include the direction of the parabola, vertex coordinates, and the axis of symmetry. By adjusting parameters a, b, and c, you can observe changes in the function's graph. The example is constructed using GeoGebra commands for objects a, b, c, d, and text objects text1 and text2. Suitable for middle school mathematics education and learning.
