The graph of f' , the derivative of f , is shown below. Use this graph of f to determine EVERY true statement. Each correct statement adds a point to your score. Each incorrect statement subtracts a point from your score. You cannot get a negative score for this question. (-4,0) (4,0) (0, -2) O f is concave up on (0, co). Of is decreasing on (-co, 0). Of is concave down on (-oo, 0). O f has an inflection point at x = 0. Of has a relative minimum at x = 0. f is increasing on (0, co)
