Functions - Absolute Value - Draggable

• Show how the graphs of \( f(x) \) and \( |f(x)| \) relate to each other
• \( f(x) \) is defined by draggable points
• Choose from:
  • \( f(x)=ax+b \)
  • \( f(x)=ax^2+bx+c \)
• Moveable points:
  • Green points (that define \( f(x)\) )
  • Black "tracer" point
