Algebra II - Today was a graph day, and people are still struggling with Domain/Range of functions. Realize that the domain is the set of all x's that can be put into the function to receive a valid answer -- if your calculator says ERROR in the table under y1, that value is NOT in the domain. The range is the set of all y's or answers that you get out -- often you can look at your graph and realize it is or is not continuing through the positive/negative numbers or zero.
No new homework, finish the take home test...
Algebra I - Test was today, and you can finish it at home. I encourage you to write out possible combinations or permutations when solving those types of problems. Writing out even a small set of the possible answers in an ordered list can help tremendously.
Homework is to finish the test.
