An open box with a square base is to be made from a square piece of cardboard 24 inches on a side by cutting out a square of side x inches from each corner and turning up the sides.Graph V=V(x)
Each side of the base will be (24-2x)
v(x) = x(24-x)^2
Wolfram's magic done here:
for a better graph, substitute (24-2x)
