How should I change “\left[4,\infty\right)” that displays the interval [4,infinity) from
content: when input5.submitted and input5.latex="\left[4,\infty\right)" “Great job!”
when input5.submitted “Your domain is incorrect, try again.”
otherwise “Find the domain of the graph at left.”
If you must use an exact string check, one thing you can do is type the correct answer into a math input, copy, and paste it into your CL.
Just a quick heads up that checking exact strings is less than ideal and can easily generate false negatives (imagine a student enters [-2, 1] instead of [-2,1]). Going to a choice, checkbox, or card sort might be a more reliable alternative here.
I’m trying to do the same thing. I copied the correct answer from a math input, but it still is recording as wrong both in the check and on the dashboard.
I know exact string check isn’t ideal, but there are only two real options in this case, so I feel like I can account for both of them.
