The graph of a function y = f(x) is shown below along with all points where the direction or concavity change. (-3,4) (8,6) (2,3) (5,-1) (8,3) (Click on the graph to enlarge it.) Based on this graph, determine all intervals where f is concave up or concave down. Express your answer as a list of comma-separated open intervals. Type NONE if there are no such intervals. f is concave up on: f is concave down on:
