For your Unit E Test, you will not be able to use a calculator on concepts 4-7. Thus, you will not need to find the extrema and intervals for the problems on your test. You will have to guesstimate and sketch the extrema (so your sketches will not be 100% accurate in that way).
However, it is VERY important that you remember how to find both extrema and intervals, thus why we are reviewing it in this lesson. Please go back to Unit B Concepts 1-2 if you need step by step help with how to find them.
Hear from Frank, Ryan, and Brianna about the importance of following directions on a test... even when it seems like it doesn't matter!
