Open a Geogebra worksheet by clicking the "+New" button on your home Geogebra screen and clicking Geogebra Math Calculators.
Go to your email and save your image to the computer. Remember where you save it!
Use the "a=2" tool to insert your Image of a real life parabola. Your image must be taken by you OR you must be in the image. YOU MAY NOT PULL IMAGES FROM THE INTERNET.
Drag your image so that the start of your parabola is located at the origin.
Right click your image, click on Settings, and check the box titled "Background Image." Reposition your image as needed by picking up Points A and B.
Use the "Point A" tool to insert 3 points onto your parabola. Make sure the points lie on your parabola, are far apart, and are non-collinear. YOU MAY NOT USE THE ORIGIN.
On a Notability document, write the three points on your parabola (labeling effectively) and use your knowledge of three variable, three equation systems to ALGEBRAICALLY (no matrix) find a quadratic equation for your parabola. Need to find a, b, and c!
Input your equation into your Geogebra worksheet to ensure your equation does, in fact, go through your three points. (If not, you did something wrong!) Make sure I can see the equation in your picture. If I cannot, please change the color of the graph. Click on the three dots located in the right corner of your equation, click Settings, choose Color, and pick a color I will be able to see.
When complete, please email this Geogebra worksheet AND your algebraic work to me. Steps: 1. Click on the options tab. Top right corner, three horizontal lines. 2. Save your worksheet 3. Go back to options, Share. 4. Email to email@example.com
