تمرين 33

Consider the contour line "Y = 3" in Figure 1A.5:
1. If Z is reduced from 9 to 3, by how much will X have to be increased to keep Y at 3?
2. If Z is further reduced from 3 to 1, by how much will X have to increase to keep Y at 3?
3. Show the numerical reasoning behind your answers to Questions 1 and 2. Then calculate the values that X must take on to keep Y at 3 if Z takes on every unit value between 9 and 1.
