Help me with this. Thank you.

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
