This example asks students to input the y-intercept, axis of symmetry, and vertex of the given function. Using GeoGebra commands such as TextField, Vertex, Polygon, and Intersect, students can visually understand the properties of quadratic functions. Suitable for middle school and above students to learn about the graph and properties of quadratic functions.

GeoGebra Commands & Parameters

  1. Textfield(a) → inputBox1
  2. Textfield(b) → inputBox2
  3. Textfield(c) → inputBox3
  4. Textfield(d) → inputBox4
  5. Vertex(g) → B, , ,
  6. Polygon(G, H, I, J) → poly1, g_1, h, i, j
  7. Textfield(k) → inputBox5
  8. Intersect(f, l, 1) → A
  9. Intersect(f, l, 2) → K

AI Drawing Prompt Reference

Draw a parabola with vertex at (0, -3), y-intercept at -1, and axis of symmetry at x=2. First, input the y-intercept -1, then input the axis of symmetry 2, and finally input the vertex (0, -3). Based on this information, draw the parabola and mark the vertex, y-intercept, and axis of symmetry. Lastly, find the points where the parabola intersects the x-axis.
