QuestionAn objective function and a system of linear inequalities representing constraints are given. Complete parts a. through c.
Objective Function $z=3 x-2 y$ Constraints $$\left\{\begin{array}{l} 3 \leq x \leq 7 \\ y \geq 2 \\ x-y \geq-4 \end{array}\right.$$ b. Find the value of the objective function at each corner of the graphed region. $\square$ (Use a comma to separate answers as needed.)
