Question 360564
1. Verify that the volume of the box is given by V = x(36-2x)^2. Determine the domain of the function.
height = x
base is 36-2x by 36-2x
--------------------------
Domain: 
Solve: 36-2x >= 0
2x <= 36
0<= x <= 18
---------------------

2. Use a graphing calculator to graph V, and use the range of dimensions from the table to find the x- value for which V(x) is maximum.

---
Maximum when x = 6
