It looks like you've uploaded an image of a computer screen displaying a graph with a blue semicircle or arc, possibly in a coordinate plane, and some instructions or explanations on the right-hand side. However, the details are a bit hard to make out from the image.

If you need help with the content in the image, could you please provide some more details or describe the specific part you'd like me to focus on? For example, you could describe any equations, questions, or tasks shown in the image.

Alternatively, if you have a clearer or more zoomed-in version of the relevant portion, feel free to upload it!
