Assume the following functions for consumption, exports and imports: C=Cg+1[YTl EX =a,, +.(YF TF) Hint IMP = :m + MY -T) - rat: where en, n, and n]. are parameters {numbers} that can loe positive or negative, and c1,1,y|,g, and y; are parameters {numbers} greater than zero. Then, ALL of the following changes can shift the aggregate demand function DOWN in the Keynesian Cross diagram: a] a lower 11]., lower u, lower on, lower T, lower G, lower I, and a lower Emp. bl a higher m, lower n, lower on, higher T, lower G, lower I, and a lower Emp. c] a lower gm, higher .60, higher on, lower T, higher G, higher I, and a higher Emp. d} a lower m, lower u, lower on, lower T, higherG, higher I, and a lower Emir. e] a higher m, higher ,6\
