**Problem 2**: Consider a map \( f : M_{n,n}(\mathbb{R}) \rightarrow M_{n,n}(\mathbb{R}) \) given by \( f(A) = A + I \) for all \( n \times n \) matrices \( A \) (where \( I \) is the \( n \times n \) identity matrix). Determine whether \( f \) is a linear operator. **Problem 3**: Determine the kernel and range of the linear operator \( L : \mathbb{R}^3 \rightarrow \mathbb{R}^3 \) given by \( L(x, y, z) = (x, x, x) \) for all \( (x, y, z) \in \mathbb{R}^3 \).
