(73) Express the surface area of a cube as a function of its volume. (74) An open rectangular box with volume V m has a square base. Express the surface area of the box as a function of the length of a side of the base. ( V is a positive fixed number.) (75) Suppose f (x) = g(h(x)). Find possible formulas for g(x) and h(x) for each of the following functions f (x). (There may be more than one answer. You just need to give one set of g and h for each f. Assume g(x) = x and h(x) = x.) (a) f(x) = (b) f(x) = P 1 (x2+4x+6)2 x + A (73) Express the surface area of a cube as a function of its volume.
