Use the IS Curve Y˜t = a − b(Rt − r), the Taylor rule R^f f t = r + m(πt − π), and the MP curve Rt = Rf f t + rho, to derive the AD curve: Y˜t = a − mb(πt − π), where a = ac + ai + ag + aex − aim − 1 − brho.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

the one below it is a function
