In Mastery Connect, if your institution has a paid Desmos upgrade, you can create a Desmos exponential function item. A Desmos exponential question requires students to plot an exponential function by moving two points on the curve. 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.
You can create any item type through the Item Editor. You can also use the Item Editor to add passages, add item-level tools, and save the item. To open and use the Item Editor, learn more about:
- Creating an item in your personal item bank
- Creating an item in the district item bank as an administrator
- Creating an item from within 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.
