!1 (TRCE)
Moving the cursor to the apex of the curve reveals that y =
2000, the maximum value, when x = 5.
This exercise shows that the volume of the box depends on the size of the cut out squares.
You can determine the best size for the cuts by observing where on the X-axis the maximum
value of Y is reached.
Check the V and x range settings before performing the operation.
