函数解析几何概率统计
①本范例演示幂函数图像、线段统计与模式计算；②涉及核心数学概念包括幂函数、线段、统计、众数、函数图像；③构造要点：使用Line、Textfield、Random、Sequence、TableText等GeoGebra命令创建图形与数据表；④适合高中数学教学，用于函数图像绘制与数据分析教学。

GeoGebra 命令及参数

  1. Line(B, A) → a
  2. Textfield(deltax) → InputBox1
  3. Textfield(deltay) → InputBox2
  4. Textfield(b) → InputBox3
  5. Random(-10, 10) → m
  6. Random(-20, 20) → n
  7. Sequence(((deltax * i), b + (deltay * i)), i, -20, 20) → list1
  8. Sequence(Segment[A + ((deltax * (i + 1)), (deltay * i)), A + ((deltax * (i + 1)), (deltay * (i + 1)))], i, -20, 20) → rises
  9. Sequence(Segment[A + ((deltax * i), (deltay * i)), A + ((deltax * (i + 1)), (deltay * i))], i, -20, 20) → runs
  10. TableText({{p, k, l}, {A7, B7, C7}, {A8, B8, C8}, {A9, B9, C9}, {A10, B10, C10}, {A11, B11, C11}, {A12, B12, C12}, {A13, B13, C13}, {A14, B14, C14}, {A15, B15, C15}, {A16, B16, C16}}, "|_r") → text2
