How do I create a Desmos logarithm function item?
In Mastery Connect, if your institution has a paid Desmos upgrade, you can create a Desmos logarithm function item. A Desmos logarithm function question requires students to graph a logarithm function by moving 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.
- 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.
