This example demonstrates the domain and range of a function. Through definition, interactive exploration, and practice, it helps students understand the basic concepts of functions. It uses GeoGebra commands such as Point, Dilate, and Segment for construction. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Point(p) → P
  2. Dilate(P, 1 - a, D) → C'
  3. Segment(P, C') → f
  4. Dilate(P, 1 - a, I) → P'
  5. Segment(P, P') → g

AI Drawing Prompt Reference

Draw a graph showing the domain and range of a function. Start by creating a point P. Then, perform a scaling operation around point P to generate point C', and connect P and C' to form the function graph f. Next, perform another scaling operation around point P to generate point P', and connect P and P' to form the auxiliary line g.
The prompt above was compiled from the original drawing commands and is for reference only.
