In the utility function U (x, y) = x y, how does the marginal utility of X depend on the amount of Y you are consuming? Use two derivatives and an inequality to figure it out. In the first blank, enter the first derivative you need to calculate, and in the second blank, enter the second derivative you need to calculate. DO NOT USE ANY SPACES OR MARKS: JUST NUMBERS AND LETTERS. In the third blank enter the inequality for the second derivative that you need to show. ENTER ONLY TWO CHARACTERS: FIRST THE INEQUALITY (EITHER > or
