We reviewed how the signs of the 1st and 2nd derivatives give us information about the shape of the graph. This material is covered in Sec 4.3 and Sec 4.5. Please work on the WebWork sets “Application – Monotonicity” and “Application – Shape of Polynomials”, which cover these topics.

See also the previous Class Recap, which includes screenshots from the textbook and some videos on these topics. I also recommended working through #18 from the Final Exam Review sheet:

You can also study the examples at the beginning of Sec 4.7: Applied Optimization.
