You can put this solution on YOUR website! An open box is to be made from a flat square piece of material 15 inches in length and width by cutting equal squares of length from the corners and folding up the sides.
Write the volume of the box as a function of x . Leave it as a product of factors; you do not have to multiply out the factors.
Volume = x*(15-2x)^2
If we write the domain of the box as an open interval in the form (a,b), then what is a ? and what is b?
a = 0 ; b = 7.5
