Solution review

So the marking scheme reflects the way mathematicians would think of this problem. I still think we should focus on what will help students improve their skills, whatever that might be. I'm not attached to a particular way of solving this question, I just wonder what best reflects our commitment to provide a useful resource to students.

I have attempted this problem considering the recommendations that are mentioned here. I plotted the graph highlighting all the special attributes in a different way. Do we think this is sufficient now?

If that's not sufficient, nothing will ever be! This will also be a great place to try using Tags once the feature is fully implemented. Thanks for the work Iain!

Awesome job! Thanks Iain.
