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?

Correctness checking the domain

They will just be entering it in a line of the graph. Here is the activity I am working on. They are asked to restrict the function on slide 3.

I experimented on this activity but didn’t have any luck:
