68 3.1. USING DERIVATIVES TO IDENTIFY EXTREME VALUES OF A FUNCTIONActivity 3.2.Suppose that g is a function whose second derivative, g ′′ , is given by the following graph.g ′′211 2Figure 3.2: The graph of y = g ′′ (x).(a) Find all points of inflection of g.(b) Fully describe the concavity of g by making an appropriate sign chart.(c) Suppose you are given that g ′ (−1.67857351) = 0. Is there is a local maximum, localminimum, or neither (for the function g) at this critical value of g, or is it impossible tosay? Why?(d) Assuming that g ′′ (x) is a polynomial (and that all important behavior of g ′′ is seen inthe graph above, what degree polynomial do you think g(x) is? Why?⊳
