# Math 251 (Phillips) Week 8 homework

• Sunday 12 November, Tuesday 14 November: There are a total of 8 optional WeBWorK assignments, roughly 7 problem each: two each on related rates, on graphing, on finding global minimums and maximums of functions, and on maximization and minimization word problems. They all have "Practice" in their names. The official due date for the first of each set is Sunday 12 November at 10:00 pm, and the official due date for the second of each set is Tuesday 14 November at 6:00 pm. Since I am not counting them as part of the grade, the significant of these dates is that you can see the answers to the problems. You can still use the problems for practice afterwards. (However, I can see whether you tried these problems, and compare with your midterm scores.)
