In collections CCGPS AA Unit 6 Lesson 4
This example demonstrates how to determine if a function is even or odd by graphing g(x) = x³ – 2x. Key math concepts include function graphs, even functions (f(-x) = f(x)), and odd functions (f(-x) = -f(x)). GeoGebra commands like LaTeX, Corner, Point and objects such as b, a, d, c, stepMax, etc., are used to construct the visualization. Ideal for high school students learning function properties.

GeoGebra Commands & Parameters

  1. LaTeX(steps) → counter
  2. LaTeX("\text{Move the slider to solve the problem.}") → text0
  3. Corner(1) → A
  4. Corner(3) → B
  5. LaTeX("\text{Graph the function.}") → text1
  6. LaTeX("\text{Visually compare the parts of the graph to the right}\cr\text{and left of the y-axis.}") → text2
  7. Point(g) → C
  8. LaTeX("\text{Drag the }\textcolor{#CC0000}{\text{red point}}\text{ along the graph and compare}\cr\text{its coordinates to those of the gray point.}") → text3
  9. LaTeX("\text{Notice that opposite values of x result in}\cr\text{opposite values of y.}") → text4
  10. LaTeX("\text{Summarize your findings.}") → text5
  11. LaTeX("\text{The function }\textcolor{#000099}{g(x)}\text{ is an odd function since it can}\cr\text{be seen from the graph that }\textcolor{#000099}{g(x) = –g(–x)}.") → text6
  12. LaTeX("\text{Use the buttons below to return to the original problem or}\cr\text{randomly generate a similar practice problem.}") → RandomizationText
  13. LaTeX((("\textcolor{#000099}{g(x)=" * g) * "}")) → Problem

AI Drawing Prompt Reference

Draw the graph of the function g(x) = x³ – 2x to demonstrate how to determine its parity. Plot the function and include a draggable point on the graph. Add text annotations to compare the graph's symmetry on both sides of the y-axis. Observe the symmetry by dragging a red point and comparing its coordinates with a gray point near the origin. Include text explaining the relationship of opposite x-values yielding opposite y-values. Conclude that the function is odd and provide justification.
