The function g is given by g(x) = f(t) dt. I -5 -4 -2 4 -2 Graph of f 26 g) On what open intervals contained in -6 < x < 6 is the graph of g both increasing and concave down? Give a reason for your answer. h) Does the graph of g have a point of inflection at x = 2? Explain why or why not. i) For each of f'(-4) and f'(2), find the value or explain why it does not exist.
