Let f be a twice differentiable function on an open interval (a, b). Which statements regarding the second derivative and concavity are true? The concavity of a graph changes at an inflection point. If f is increasing, then the graph of f is concave down. If f" (c) is negative, then the graph of f has a local minimum at x = c. The graph of f is concave up if f" is positive on (a, b). The graph of f has a local maximum at x = c if f" (c) = 0.
