Activity 1: Parabola Around Us

There are a lot of objects around us that looks like a parabola. For this activity, you will explore the rich arts and architectures of the Philippines that have parabolic design.
1. Find an example of a real parabolic curve found in the Philippines
2. Research about its origin and its actual size. 3. Using any graphing applications (android apps, internet app, computer software, etc.), insert the picture into the rectangular plane and adjust the scale to its actual size.
4. Insert a point for the vertex of your picture and determine its coordinates.
5. Locate for additional points that your graph pass through. Determine the coordinates of these points.
6. Using these points, find the equation in general form of the parabola formed by your picture.

Activity 2: Reflection

The challenges you are facing during graphing of functions, not only quadratic, can be eased out by using technology. A lot of graphing tools can be used to graph functions in seconds. What is your stand in using graphing tools during lessons on graphing? Do you think it is necessary to learn first the graphing manually before jumping into technology? On what instances is technology the best option in graphing functions?​
