2. (This problem derives the general result that any polynomial function is of a lower asymptotic order than any exponential function.) First, we prove a special case. Suppose that we have two functions, f(n) = n² and g(n) = 2". We will prove that f(n) = O(g(n)). (e) (Slightly harder) Find a constant c₁ such that f(ni) ≤ cig(n1), where n₁ is defined as in part (d). (f) (Harder) Show that, for any n ≥ n₁, it must be the case that f(n) ≤ cig(n) ⇒ f(n+1) ≤ cig(n+1), and therefore nk = O(a") for all k, a ≥ 1.

PER-UNIT COST (Dollars) Jouet is a profit-maximizing firm producing toy trains-a capital-intensive good-which are sold in its home country, France, and abroad in Russia. Jouet chose foreign production as a method of penetrating the Russian market and has to decide whether it is more efficient to directly invest in ussia to establish a production subsidiary or to license the technology to a Russian firm to produce its goods. n the following graph, AVCR is the average variable cost curve of a Russian firm producing toy trains. (This curve represents costs such as labor nd materials.) The curve ATCsidiary represents the total unit costs Le Jouet will face if it establishes a subsidiary in Russia.

It is estimated that a grocer’s daily profit from the sale of two brands of cherry juice is given by thefunction:P(x,y) = (x - 30)(70 - 5x + 4y) + (y – 40)(80 + 6x – 7y) centswhere x is the price per can of Brand V Juice and y is the price per can of Brand Triple V Juice. CurrentlyBrand V Juice sells for 50 cents per can and Brand Triple V Juice sells for 52 cents per can.i. Use marginal analysis to estimate the change in the daily profit that will result if the grocer raises theprice of Brand Triple V by one cent per can while keeping the price of Brand V unchanged.ii. Find a stationary point of the daily profit function. Classify this stationary point.
