TEACHER: And that is how you find the MIN/MAX on your calculator. *BOOM* Drop the mic! STUDENT: What do I put in Y1? _ _ _ _ _ _ _ _ _ No more of this! Give your students a great reference sheet to put in their notebook and NEVER ask you the keystrokes again!
Every year my Algebra 2 students get really confused by the whole "Left Bound / Right Bound" thing on the graphing calculator. This is especially true when finding zeros. I've found it really wordy trying to explain that Left and Right Bound will sometimes be above the x-axis and will sometimes be below it, so this year I am going to hand out the above reference sheet to help. If you think this sheet would help your students, you can find the file called "left bound right bound"
