This example demonstrates how to use GeoGebra to plot the solution set of inequalities, involving concepts like inequalities, fractions, angles, binomial distribution, bar charts, and indefinite integrals. It utilizes commands like Polygon, LaTeX, Element, Textfield, If, and objects such as TryAnother, viewBox, Initialize, QUESTION, INSTRUCTIONS, TEXT, HowDidIDo, isChecked, correctA, incorrectA, numQuestions, questionList, questionListIndex, questionNum, A1, A2, A3, A4, A5, B1, B2, B3, B4, B5, bPrompt, aPrompt, textAX, textAY, textBX, textBY, ax, ay, bx, by, axBox, ayBox, byBox, bCoords, aCoords. Suitable for high school mathematics students and teachers for teaching demonstrations and explorations.

GeoGebra Commands & Parameters

  1. Polygon({(-11, -11), (-11, 11), (11, 11), (11, -11)}) → viewBox
  2. LaTeX((((("\text{" * QUESTION) * "\\") * INSTRUCTIONS) * "}")) → TEXT
  3. Element(questionList, questionListIndex) → questionNum
  4. LaTeX("\text{Enter the coordinates for Point \(B\),\\a point that \textbf{is not} part of the solution set.}") → bPrompt
  5. LaTeX("\text{Enter the coordinates for Point \(A\),\\a point that \textbf{is} part of the solution set.}") → aPrompt
  6. Textfield(textAX) → axBox
  7. Textfield(textAY) → ayBox
  8. Textfield(textBY) → byBox
  9. LaTeX("B(\hspace{47},\hspace{47})") → bCoords
  10. LaTeX("A(\hspace{47},\hspace{47})") → aCoords
  11. Textfield(textBX) → bxBox
  12. LaTeX("\text{Any point that lies within the shaded region,\\or on a solid boundary, satisfies the inequality.}") → aFeedback
  13. If(Defined[A], A2(A), false) → C2
  14. If(Defined[A], A3(A), false) → C3
  15. If(Defined[A], A4(A), false) → C4
  16. If(Defined[A], A5(A), false) → C5
  17. If(Defined[B], ¬(A2(B)), false) → D2
  18. If(Defined[B], ¬(A3(B)), false) → D3
  19. If(Defined[B], ¬(A4(B)), false) → D4
  20. If(Defined[B], ¬(A5(B)), false) → D5
  21. Element(C2:C5, questionNum) → isAcorrect
  22. Element(D2:D5, questionNum) → isBcorrect
  23. LaTeX("\text{Any point that lies within the unshaded region,\\or on a dashed boundary, does not satisfy the\\inequality.}") → bFeedback
