This example demonstrates the graphing of parabolas in the form (x-h)^2=4p*(y-k) and explores their properties. Key math concepts include parabola equations, vertex, focus, directrix, and the geometric meaning of parameter p. GeoGebra commands like Point, Segment, and Distance are used to construct elements such as vertex V, focus F, and directrix, with sliders to dynamically adjust parameters h, k, p. Suitable for high school coordinate geometry instruction to visually understand how parameters affect the shape of the parabola.

GeoGebra Commands & Parameters

  1. Point(f) → A
  2. Segment(F, A) → b
  3. Distance(F, A) → c
  4. Distance(F, A) → distanciaFA
  5. Point(Circle[A, distanciaFA]) → B
  6. Segment(A, B) → e

AI Drawing Prompt Reference

Draw a parabola showing its properties including vertex, focus, and directrix, with sliders to dynamically adjust parameters h, k, p. Illustrate the line segment between the vertex and focus, the distance from the focus to the vertex, and a circle with this radius intersecting the parabola to find another point. Connect the vertex and this intersection point with a line to visualize how parameter changes affect the parabola's shape.
