How do I create a Desmos hyperbola item?
In Mastery Connect, if your institution has a paid Desmos upgrade, you can create a Desmos hyperbola item. A Desmos hyperbola item requires students to graph a hyperbola by moving points that control the vertex, center, asymptotes, and orientation. After you select the question type, you can use the math editor to add details for the question, view a student preview, and validate answers.
- If you do not see the Desmos Items (Paid Upgrade) section in the Question Type drop-down menu, your institution does not have a paid Desmos upgrade.
