How do I create a Desmos Polynomial by Points question in an item bank?

If your institution has a paid Desmos upgrade, you may be able to add a Desmos Polynomial by Points question to an item bank. After you select the question type, you can use the LaTeX editor to add details for the question, view a student preview, and verify auto-grading is working correctly. Once the question is published to an item bank, you can add the question to an assessment.

Note: 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.
