7. Suppose you know that f(x) is an odd function on the domain of all real numbers and that the function is concave up on the intervals 0 < x < 3 and 5 < x and concave down on the interval 3 < x < 5.

List ALL intervals on which the function fx is concave up and ALL intervals on which the function fx is concave down; explain how you know these to be correct.
