Step 1
Step 0
Open a Geogebra worksheet by clicking the "+New" button on your home Geogebra screen and clicking Geogebra Math Calculators.
Step 0.5
Go to your email and save your image to the computer. Remember where you save it!
Step 1
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.
Step 2
Drag your image so that the start of your parabola is located at the origin.
Step 3
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.
Step 4
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.
Step 5
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!
Step 6
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.
Step 7
When complete, please email this Geogebra worksheet AND your algebraic work to me.
