Question

Noah finds an expression for V(x) that gives the volume of an open-top box in cubic inches in terms of the length xin 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.Write an expression for V(x).

Answer 1

Step-by-step explanation:

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

The x values starts from -1 and ends at 5

The domain of the graph is from 0 to 4 (i.e. x-values 0 to 4 have corresponding y-values on the graph)

x-values 0 to 2.5 have corresponding non-negative y-values

Other values of x have corresponding negative y-values

The maximum of the graph is at y = 15
