FunctionCoordinate GeometryInequality
This example demonstrates the solution set of quadratic inequalities on a coordinate plane. It involves core mathematical concepts such as quadratic function graphs, inequality solving methods, and interval notation. The construction uses GeoGebra commands like Point, Ray, Expand, and objects including A, a, C, i, B, b, f, ineq, g, text1, text2, p, h, text4, q, c, text5, text6, d, e, text3. It is suitable for high school mathematics teaching, helping students understand the geometric meaning and solution steps of quadratic inequalities.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Ray(A, C) → i
  3. Point(i) → B
  4. Expand(f) → g

AI Drawing Prompt Reference

Draw a coordinate plane, first take a point A on the x-axis, then draw a ray i from A. Next, take a point B on the ray. Finally, expand a quadratic function f to get its expanded form g.
The prompt above was compiled from the original drawing commands and is for reference only.
