5. An objective function and a system of linear inequalities representing constraints are given. Complete parts a 45 through c. 12 Objective Function z = 4x - 2y Constraints 3SXS8 y23 x- y2 - 3 a. Graph the system of inequalities representing the - 15 12 -9 TR 15 constraints. Use the graphing tool to graph the system. b. Find the value of the objective function at each corner of the graphed region. (Use a comma to separate answers as needed.) c. Use the values in part (b) to determine the maximum value of the objective function and the values of x and y at which the maximum occurs. The maximum value of the objective function is Find the values of x and y at which the maximum occurs. X=
