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.
