4. We want to make an open-top box by cutting out corners of a square piece of cardboard and folding up the sides. The cardboard is a 9 inch by 9 inch square. The volume V(x) in cubic inches of the open- top box is a function of the side length x in inches of the square cutouts. a. Write an expression for V(x). b. What is the volume of the box when x = 1? c. What is a reasonable domain for V in this context?
