b) Let aggregate national income be given by Y, = C; + l4 + G Where C, I and G are consumption, investment and government expenditure. Assume that consumption is given by C = mY, Investment is given by Ik = 1 + a(Yc-1 – Ye-2) And government expenditure declines over time according to G = Go(1 – 8)', 0 < 8 <1 Where 8 is the exogenous rate of decline of government expenditure Derive the linear second order difference equation. (i) Solve the difference equation.
15. Let a be a real number. We will explore the derivatives of the function f(x) = eax. By using the chain rule, we see (a) What is Recall that the second derivative of a function is the derivative of the deriva- tive function. Similarly, the third derivative is the derivative of the second derivative. (b) What is d² dx² d3 C030 BY NO SA d dx = aeax (eax), the third derivative of eax? (c) Let n be a natural number. Make a conjecture about the nth derivative dn of the function f (x) = eax. That is, what is (eax)?
