该范例演示了半衰期函数的图像。涉及的核心数学概念包括指数函数和函数图像。通过使用GeoGebra命令如Textfield、Point、Intersect等,可以构造出半衰期函数的图像。适合高中及以上学生学习指数函数和半衰期概念。
GeoGebra 命令及参数
Textfield(a_0) → InputBox1Textfield(k) → InputBox2Point(A) → CIntersect(A, b, (399.99999999999994, 200)) → DIntersect(A, c, (800, 100)) → EIntersect(A, d, (1200, 50)) → FIntersect(A, e, (1600, 25)) → G
