2) I would put 20 
the sum of the area under the graph between x = 1 and x = 6
picture the rectangle  (6-1) across and (4-0) up 5 *4 = 20

triciaal · Answer

not the solution directly but information from the graph
(3,3) at 4 increasing (5,4) (6, 4) no change in slope (7,3) y decreases 
therefore went through a maximum at y = 4
