Webb) f is concave up for values of x such that f" is positive. According to given graph f" is positive on interval (-2 , 1) and (3 , +infinity). c) f is concave down for values of x such that f" is negative. Using above graph, f" is negative on (-infinity , -2) and (1 , 3). d) Points of inflection are located at values of x where f" changes sign.

WebJul 25, 2024 · Below are three pairs of graphs. The top graph is the original function, f (x), and the bottom graph is the derivative, f’ (x). What do you notice about each pair? If the slope of f (x) is negative, then the graph of f’ (x) will be below the x-axis. If the slope of f (x) is positive, then the graph of f’ (x) will be above the x-axis.
