Graph the system of inequalities. Name the coordinates of the vertices of the feasible region. Find the maximum and minimum values of the function for this region.
3 ≤ y ≤ 6
y ≤ 3x + 12
y ≤ -2x + 6
f(x , y) = 4x - 2y

• The maximum value is 0 at (0, 6). The minimum value is - 20 at (-3, 3).
• The maximum value is 0 at (-3, 3). The minimum value is - 20 at (0, 6).
• The maximum value is 0 at (-2, 6). The minimum value is - 20 at (1.5, 3).
• The maximum value is 0 at (1.5, 3). The minimum value is - 20 at (-2, 6).
