GeoGebra Image Plotting Techniques

The video tutorial guides students through an activity using GeoGebra to model real-life objects with quadratic functions. Students are instructed to select an image that can be modeled by a parabola, upload it to GeoGebra, and plot points on it. They then create a list of these points, fit a polynomial to the data, and adjust settings for better accuracy. Finally, students are asked to take a screenshot of their work and think of follow-up questions that can be answered using the model. The tutorial emphasizes hands-on learning and application of mathematical concepts.
