1} Given that f(x) = x\" , evaluate f(0), f'(0), andf"(0). Is there a point of inflection at x = 0? Why or why not? 2} Given that f(x) = l (x+ If, find the intervals of increasing/decreasing, the concavity, and inflection points. 3} Given that f'(x) = x2 x6, sketch the graph of f(x) . Note that f(x) is a third degree polynomial. Use the second derivative to help. Answers may vary
