There is this thread:

Correctness checking the domain

I want students to restrict the domain of a function in a graph between -2 and 4. So the correct answer would be f(x)=2x+3 {-2 ≤ x ≤ 4}. Is there a way to check this and have it display a checkmark in the dashboard?

I tried something with rawExpression and with simpleFunction, but couldn’t get the restrictions to work using the CL.
