This example demonstrates the graph of a piecewise function and how to use GeoGebra to draw a confidence interval. The commands used include Segment (line segment), OrthogonalLine (perpendicular line), Circle (circle), Intersect (intersection), and AngularBisector (angle bisector). Suitable for high school mathematics, particularly in function and statistics courses.

GeoGebra Commands & Parameters

  1. Segment(A, B) → f
  2. OrthogonalLine(A, f) → g
  3. Circle(A, B) → c
  4. Intersect(c, g, 2) → C
  5. OrthogonalLine(C, g) → h
  6. OrthogonalLine(B, h) → i
  7. Intersect(h, i) → D
  8. AngularBisector(B, A, C) → j
  9. AngularBisector(C, D, B) → k
  10. AngularBisector(D, B, A) → l
  11. Intersect(j, k) → E
  12. Intersect(j, k) → F
  13. Intersect(j, k) → G
  14. Intersect(j, k) → H
  15. Intersect(j, k) → I
  16. Intersect(j, k) → J
  17. Intersect(l, j) → K
  18. Circle(K, D) → d
