You are given the graph of a functionf.Thexy-coordinate plane is given. The curve enters the window in the second quadrant nearly horizontal, goes down and right becoming more steep, is nearly vertical at the point(0, 1),goes down and right becoming less steep, crosses thex-axisat approximatelyx= 1,and exits the window just below thexaxis.Determine the intervals where the graph offis concave upward and where it is concave downward. (Enter your answers using interval notation.)

concave upward: _________

concave downward: _________

Find the inflection point off. (If an answer does not exist, enter DNE.)

(x,y) =
