Noah finds an expression for V(x) that gives the volume of an open-top box in cubic inches in terms of the length x in inches of the cutout squares used to make it. This is the graph Noah gets if he allows x to take on any value between -1 and 5.

The domain of a graph is the possible x-values of the graph, while the range is the possible y-values.

From the attached graph (see attachment), we have the following observations.

Because the volume of a box cannot be negative, the x-values to use must correspond to non-negative y-values.

Hence, the proper domain of Noah's graph should be 0 to 2.5

And the maximum of the graph is at y = 15

for more appropriate it would be 0-2.5, and the max is 15
