I don’t understand the material. Where is the graph concave up or concave down, where is it increasing or decreasing, I just don’t get it. Doing more practice problems doesn’t seem to help if I keep getting them wrong and still don’t understand where I went wrong. I’m not used to this. Someone help?
Google “calc 1 graphing” or something similar. My search brought up this page from a university: https://www.math.ucdavis.edu/~kouba/CalcOneDIRECTORY/graphingdirectory/Graphing.html
As well as a SparkNotes guide and some Khan Academy videos.
