Staff Review
This video starts off with an excellent summary / review of graphical features of functions, including increasing / decreasing behavior, concave up / concave down, horizontal asymptotes, vertical asymptotes, vertical tangents, cusps, and corners. Then, you wil learn how to sketch a graph by finding its features using methods we know. This video can get very complex, as almost everything you have learned so far in Calculus comes into play. If you understand this lesson, then you know you are doing well. -
