I have an internal assessment to do that is crucial for my Math end of year grade. I have gotten a 4/20 on it and I have a chance to correct it. I will send you the feedback that my teacher has sent to me together with the work I have done. Some parts have AI so please paraphrase them and correct them. I need tables and also for you to expand this a lot further by using math in a meaningful manner and not just statistics. You can find more data by searching. The topic has to do with NBA and basketball in general. I believe if you have been watching some basketball it will be more helpful for you to finish this assignment. I will send you the files and the feedback when I select you. Thank you very much!
Provide detailed, specific context to ensure the most accurate and helpful AI assistance possible.

A function that is:
bounded on compact intervals except possibly at finitely many points, and
has a finite number of discontinuities,
is Riemann integrable.
