Question

The region of possible solutions is not bounded: thus, there may not be both a maximum and a minimum. After graphing the region of possible solutions and finding each corner point, you can determine if both a maximum and a minimum exist by choosing two arbitrary values of z and graphing the corresponding lines, as discussed in the section "Why the Corner Principle Works."

The objective function 

z = 4x + 7y

 is subject to the constraints

3x + y ≥ 12
x + y ≥ 6
x ≥ 0   and   y ≥ 0.

Find the following. (If an answer does not exist, enter DNE.)

(a) the point at which the maximum occurs (if there is such a point)
(xy) = 
 
  ,  
 


(b) the maximum value


(c) the point at which the minimum occurs (if there is such a point)
(xy) = 
 
  ,  
 


(d) the minimum value
