FunctionInequalityGraphing
This example demonstrates graphing solution sets of inequalities on a number line. It involves core math concepts like inequalities, number line representation, and intervals. Construction uses GeoGebra objects such as a, b, text1, c, d, e, etc. Suitable for middle school and above learning inequality representation and function graphing applications.

GeoGebra Commands & Parameters

  1. Numeric a(0.55)
  2. b(x) = x > a
  3. c(x) = x ≥ a
  4. d(x) = x < a
  5. e(x) = x ≤ a
  6. Boolean f(true)
  7. Boolean g(false)
  8. Boolean h(false)
  9. Boolean i(false)
  10. Numeric lower(-1.6)
  11. Numeric upper(2.6)
  12. j(x) = lower < x < upper
  13. Boolean k(false)
