Dual Parabolas Demo

This example demonstrates the properties and intersection points of two parabolas defined by p=3. It involves core mathematical concepts such as parabola definition, focus, directrix, parametric equations, and coordinate geometry. The construction uses GeoGebra commands focusing on Focus, parameters a and d, Vertex, vertex, and eccentricity e. Suitable for high school students and teachers to understand parabolic geometry and parameter effects, or for analytical geometry instruction.
