All numbers are in billions of dollars. The interest rate and the level of investment spending in the economy are at point C on the investment demand curve. To achieve the long-run goal of a noninflationary full-employment output Qf in the economy, the Fed should: decrease aggregate demand by increasing the interest rate. make no change in the interest rate. increase aggregate demand by decreasing the interest rate. increase aggregate demand by increasing the interest rate.
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)). • port (a). (c) Show that, for any n ≥ no, it must be the case that f(n) ≤ cog(n) = f(n+1) ≤ cog(n+1). Precisely state the argument by induction that n² = 0(2¹). Now, define f(n) = nk where k ≥ 1, g(n) = a", where a ≥ 1. (d) (Slightly harder). Argue that, for any k and a, there exists some n₁ such that : (1₁+¹)* < a.

(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.
