y > 0 for -2 < x < 4
Therefore, the graph is opened in the downward direction with the peak at the point with coordinate (1, 3)
The legs of the graphs are straight lines with slopes = -1, and 1 respectively, before and after the maximum point of the graph
The table of values used to sketch the graph with Microsoft Excel is given as follows;
x y
-3 -1
-2 0
-1 1
0 2
1 3
2 2
3 1
4 0
5 -1
