After reading all the available information carefully, prepare a two page (double-spaced) essay and answer the following questions:
assume that we have the following data:
c=100+0.50y
ip=100-20r
mt=0.10y
ms=100-10r
m=80

a. build the is-lm function.
b. if we assume an increase in investments by 100 units, calculate again the is-lm functions.
c. the intersection of is-lm functions defines four areas. analyze the behavior of the markets for goods and money for each area.

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
