1. Consider a function that is (i) decreasing in a; (ii) decreasing in b; and (iii) strictly quasiconvex. (a) Draw quadrant I of the Cartesian coordinate plane. Your graph should be large enough to work with and make sense of (perhaps one-quarter of the page). (b) Label the axes of the graph you drew in part (a). (C) Put a point in roughly the middle of your graph in part (a). Label the point A. (d) Through point A in your graph, draw a level set of the function described above. (e) In your graph, shade in the better set of point A
