Three Graphics Views: f(x), f'(x), and f''(x) Side-by-Side

① This example uses three side-by-side graphics views to simultaneously display a function f(x), its first derivative f'(x), and its second derivative f''(x), allowing direct visual comparison of the original function and its derivatives. ② Core mathematical concepts include derivatives, function graphs, extrema, inflection points, and how the sign of derivatives affects monotonicity and concavity. ③ Construction highlights: The GeoGebra command Textfield creates a text input box, defining an object a (representing f(x)); the derivatives f'(x) and f''(x) are automatically generated; InputBox1 lets users dynamically edit the function expression, and three separate Graphics Views are bound to display each function. ④ Suitable for high school to early college students learning calculus, this example serves as an interactive demonstration for classroom teaching or self-study, and can be a template for building dynamic calculus lessons.
