x x+7 (4 points) Let f(x) = = . Find (a) the intervals on which fl is increasing, (b) the intervals on which fl is decreasing, (c) the open intervals on which fl is concave up, (d) the open intervals on which fl is concave down, and (e) the x-coordinates of all inflection points. (a) f is increasing on the interval(s) Note: Enter a comma-separated list of closed intervals [a, b] or semi-open intervals (-, a] or [b, ). (b) f is decreasing on the interval(s) Note: Enter a comma-separated list of closed intervals [a, b] or semi-open intervals (-, a] or [b, ). (c) fis concave up on the open interval(s) Note: Enter a comma-separated list of open intervals. (d) f is concave down on the open interval(s) Note: Enter a comma-separated list of open intervals. (e) the xl coordinate(s) of the points of inflection are
