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.
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.
