I could be wrong, but I think you can use the HTML code associated with the plot in the switch function.  Which would randomly select the HTML code for a given plot.  This in effect will do what you want.

Here is a question that uses the letter "U" to formulate a union of two intervals to specify the domain of a function:

The question(.zip) can be downloaded here:  https://naitca-my.sharepoint.c...

***notes:  the question ignores annoying spaces the student might add into their response

This is what the question looks like:

Writing grading code to accommodate for the union symbol can cause problems depending on which version of maplenet your are running.  I would suggest a much easier approach:  Have students use the letter "U" on the keyboard.  This way you can simply do a string comparison.

For a domain question, you could try the following:
****  note1:  the grading code was written to accomodate for "inf" as infinity if you were to modify the question.

**** note2:  the grading code ignores annoying extra spaces the student might add in.

Preview:

I might suggest an animated 3d plot.  This way the object moves on its own to show all sides.  Animated plots will work with the plotmaple command.

I would suggest something to the effect of the following:  here is a .zip of the question above that can be imported:  https://naitca-my.sharepoint.c...
ALGORITHM BELOW

------------------------------------------------------------------

$degreeF=range(2,5,1);
$degreeG=range(2,5,1);

$randomMark=rint(100000);
$callout=maple("
with(RandomTools):
randomize($randomMark):
functionF:=Generate(polynom(nonzeroint(range=-10..10),x,degree=$degreeF)):
functionG:=Generate(polynom(nonzeroint(range=-10..10),x,degree=$degreeG)):
answer:=functionF+functionG:
generateStrings:=seq(convert([functionF,functionG,answer][i],string),i=1..3):
generateLatex:=seq(latex([functionF,functionG,answer][i],output=string),i=1..3):
[generateStrings,generateLatex];
");
$functionF=switch(0,$callout);
$functionG=switch(1,$callout);
$functionAnswer=switch(2,$callout);
$functionFlatex=switch(3,$callout);
$functionGlatex=switch(4,$callout);
$functionAnswerLatex=switch(5,$callout);

---------------------------------------------------------------------------------------

Essentially this will allow you to generate random functions, and automatically convert the function to latex that can be put directly into the question.  This avoids having to use the equation editor.

Here are two avenues of support:

• Use the HTML question type to communicate with external pages: https://teachingservices.nait....
• I believe Digital Ed might be working on a way to import LMS assessment content into Mobius.

To the best of my understanding the ability to re-score miss-keyed responses is a feature request (https://ideas.digitaled.com/) and not part of the current release.  Also, and this part is something I am not 100% sure of, if Student A attempted the original question they will see the original question in their gradebook.  While if Student B attempted the "revised" question they will see the "revised" question in their gradebook.  It would be far more confusing if everyone saw the revised question, even though half of them were graded with miss-keyed answer.  To this end, I would recommend using the "edit question comment" field when manually correcting the miss-keyed student responses.

Hi Sarah,

4 separate calls for plots shouldn't be sluggish, I would follow up with support on that concern, however you also have the following option:

I have used this many times..  use the Plots:-display command to display multiple color plots on the same grid, with a legend indicating what choice is what line.  For example redLine=choiceA blueLine=choiceB..   etc

Here is a simple to follow example that illustrates this and also uses an algorithmic answer in the multiple choice:

Hope it works out for you,

Mark
