Saved a checkpoint:
I changed the wording in the advice a bit.
Otherwise, looks good!

Thank you for the feedback, I've done pretty much everything you've asked but I am unable to fix the scroller as it is an internet explorer issue. I have also left the last line of e) because i think it is still a useful piece of extra information and eads nicely onto the nexgt question.

just a few things to comment on:
maybe you could consider changing your title to include a reference to composite functions?
I don't know whether you'd consider a longer statement, maybe explaining what an inverse is and how you find one from an equation/what it might be used for
question d I would maybe separate f(x)...\\and\\g(x)... and then align them
in f you have a comma after c) you either need to remove it or place a comma after your equation
in f typo 'exsist'
with your answer s for f I'm unsure as to whether you need all those full stops as they are not full sentences.
in you advice especially part a it might be nice to have a little explanation as to what you are doing eg what is y
part a of advice is not currently a sentence, maybe you want to expand the first line of both sightly
I'm not sure you need to repeat your questions down in the advice but that is up to you
maybe in advice of d state what g(x) is before you subsitute it
in the advice of e there is a scroller, not sure what it is for and why it is there
not sure you need the last line of e is necessary as it isn't the final solution

Thank you for the advice, I've acted on those two points, let me know if you think I should make any further alterations.

Use \left( and \right) around fractions to make sure the brackets stretch to the correct height.
In the advice for the final part, I would use an identity symbol ($\equiv$), and maybe preface the identity with "it is always true that"

I've done that simplification
Vicky Hall 2 years, 5 months ago
If your expression is $\displaystyle\frac{\frac{(xa)}{b}+c}{bd}$, rearrange it to $\displaystyle\frac{xa+bc}{bd}$. Type this into the marking box as
(x+{a+b*c})/{b*d} and it should simplify nicely.

The expected answers are not simplifed here. For example, I entered $\displaystyle \frac{x+6}{10}$ (which was marked as correct) but the expected answer displayed as $\displaystyle \frac{\frac{x2}{2}+4}{5}$. This is the same in the advice, except here the answer displays as $\displaystyle ((x2)/2+4)/5$, which is a nightmare to read! Have the advice display the solution in its simplest form and use \frac.

To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.
In order to create a variable replacement, you must define at least one variable and one other part.

The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
