section (measuring x inches to a side) and costing $100 to ship, the function V(x) = x²(400 – 4x) gives the volume of the box (in cubic inches). Find the values of x that are physically possible for such a box (called the relevant domain). Enter your answer as an interval with open parentheses: Use the first derivative to determine where the function V(x) is decreasing (within the relevant domain). Enter your answer as an interval with open parentheses: Use the second derivative to determine where the function V(x) is concave up (within the relevant domain). Enter your answer as an interval with open parentheses: Find the maximum volume we can ship for $100 (having square cross-section). cubic inches

Please help with the third and fourth part.
Transcribed Image Text:Allouette Shipping Company has a peculiar fee schedule. When determining the price to ship a rectangular
box, they measure the girth plus the length and multiply the result by $0.25. For a box with a square cross-
section (measuring x inches to a side) and costing $100 to ship, the function
V(x) = x²(400 – 4x)
gives the volume of the box (in cubic inches).
Find the values of x that are physically possible for such a box (called the relevant domain). Enter your
answer as an interval with open parentheses:
Use the first derivative to determine where the function V(x) is decreasing (within the relevant domain).
Enter your answer as an interval with open parentheses:
Use the second derivative to determine where the function V(x) is concave up (within the relevant
domain). Enter your answer as an interval with open parentheses:
Find the maximum volume we can ship for $100 (having square cross-section).
