The graph to the right shows a region of feasible solutions. Use this region to find maximum and minimum values of the given objective functions, and the locations of these values on the graph. (@) z=4x+3y (b) z=2.25x + 0.50y (&= (a) What is the maximum of z = 4x + 3y? Select the correct answer below and, if necessary, fill in the answer boxes to complete your choice. O A. The maximum value of the objective function z=4x + 3y is and is located only at the point(s) Type exact answers. Use a comma to separate answers as needed.) 0 B. The maximum value of the objective function z=4x+3yis | . Itis located at the points and at all points on the line segment connecting them. (Type exact answers. Use a comma to separate answers as needed.) () . The maximum does not exist. (8,3)
