![**Finding Minimum and Maximum Values of a Function with Constraints**
Consider the function \( f(x, y, z) = x^2 + y^2 + z^2 \), subject to the constraint \( x + 6y + 7z = 6 \). Your task is to determine the minimum and maximum values of this function given the constraint.
**Instructions:**
- Use symbolic notation and fractions where needed.
- If an extreme value does not exist, enter "DNE" (Does Not Exist).
**Answer Fields:**
- Minimum:
\[ \frac{43}{2} \]
*Note: This answer is marked as incorrect.*
- Maximum:
\[ \text{DNE} \]
**Explanation:**
In this problem, you'll be applying techniques from multivariable calculus, such as Lagrange multipliers, to find the extrema under the given constraint. Ensure your calculations are exact and use proper fraction notation where needed. If you determine that there is no maximum value possible, indicate this with "DNE."
Remember, it's crucial to verify your solutions and ensure they adhere to the constraint \( x + 6y + 7z = 6 \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa40558bc-afda-4e2b-be1a-c4211c27f73c%2F4e46e9e9-72ca-47f9-a552-28dc85b33846%2Fmkwigs_processed.png&w=3840&q=75)
