Question
An objective function and a system of linear inequalities representing constraints are shown on the right.

**Objective function:**  
\( z = x + 6y \)

**Constraints:**  
\( x \geq 0, \, y \geq 0 \)  
\( x + y \geq 1 \)  
\( 3x + 4y \leq 12 \)  
\( 4x + 3y \leq 12 \)

---

**a.** Graph the system of inequalities representing the constraints. Choose the correct graph below.

- **Option A:** Incorrect graph 
- **Option B:** Incorrect graph
- **Option C:** Correct graph

**Explanation of Graph C:**  
The graph displays a shaded feasible region that satisfies all given constraints. The x-axis ranges from -2 to 12, and the y-axis ranges from -2 to 12. The boundaries of the shaded region correspond to the constraints. The lines are drawn for each inequality constraint, with the shaded area indicating the feasible solutions.

---

**b.** Find the value of the objective function at each corner of the graphed region.

The values of the objective function are \( \underline{\quad} \).  
(Type an integer or a fraction. Use a comma to separate answers as needed.)
