![### Linear Algebra Problem on Linear Transformation
**Problem 2:**
Linear transformation \( L \) is given by the formula below. Find the matrix of \( L \), the domain, the co-domain, the kernel, and the range using methods of linear algebra. Make sure to show all work and clearly mark the answers.
#### Question a.
\[ L(x, y) = \langle x - y, x + y, -x + y, y \rangle \]
#### Question b.
\[ L(x, y, z, w) = \langle x + y + z + w, x - w \rangle \]
For each question, you will need to:
1. **Find the Matrix Representation of \( L \):** Write the transformation in matrix form.
2. **Determine the Domain:** Identify the vector space from which the inputs to the transformation \( L \) are from.
3. **Determine the Co-domain:** Identify the vector space where the outputs of the transformation \( L \) land.
4. **Calculate the Kernel (Null Space):** Find all input vectors that map to the zero vector under \( L \).
5. **Calculate the Range (Column Space):** Determine the set of all possible output vectors of the transformation \( L \).
Make sure you label and organize your steps clearly to ensure complete understanding of how each property of the linear transformation is determined.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff003da25-8c7d-4491-8329-a317b002c309%2Fb2c67310-9e18-4d21-a842-6bd4df3b2b26%2Fh79abw5_processed.png&w=3840&q=75)
