## How do I create a Desmos polynomial by points item?

In Mastery Connect, if your institution has a paid Desmos upgrade, you can create a Desmos polynomial by points question item. A Desmos polynomial by points question requires students to graph a function and identify the polynomial as a response to a stimulus. 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.

Notes:

• 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.
• District and school administrators (admins) can also create items directly in the district item bank
