I think, that the answer in Q6 is more informative than in the other questions. E.g. you shows, that the two x-values will give a certain utility. I also like the way, you describe what you have done in the code.

Your answer to Q2 seems the most elegant. The code is short and simple, and the results are displayed in an easy to understand manner. Question 5A is similar, just need a clarification on the print as to the values found are of those for x1A.

I really like your answer to question 8. It is easy to understand, enough explanation. However, it would be better if you make the graph result more concisely.
