Minimum or Maximum Function

I have an exam on Wednesday 20 questions(I believe or less), my teacher is so PICKY so the answers to the questions she will give us should be exactly how she presents it in both recorded meetings below. The document I have attached is the topics for the final exam and the recordings are here going over them. she is very picky with her answers and deducts points for  not doing it the same way and format. 

FINAL = Wednesday – May 6th – 10 am to 1 pm
