all parts please

For this question, suppose that i, G, and Y*are xed. Also, for simplicity, assume that NX is zero initially. (a) Draw a diagram representing the initial equilibrium in the goods market. Denote the initial equilibrium by point A. (b) Suppose that the government increases T. Denote the new equilibrium by point B. What Will be the effect of this change on Y, C, I , and NX? (c) How can an exchange rate policy stabilize output when T increases as in (b)? Denote the new equilibrium by point C. Compare Y, C, I , and NX under points A and C
