Question
![**Problem A. Consider the linear transformation**
\[ T: \mathbb{R}_1[x] \rightarrow \mathbb{R}_1[x] \]
given by
\[ T(a + bx) = (a + b) + ax \]
(A1) Is \( T \) cyclic?
(A2) Is \( T \) irreducible?
(A3) Is \( T \) indecomposable?
---
**Explanation:**
- **Linear Transformation**: The function \( T \) is a linear transformation mapping polynomials of degree 1 to polynomials of degree 1.
- **Definition**: \( T \) is defined by the rule \( T(a + bx) = (a + b) + ax \), where \( a \) and \( b \) are constants, and \( x \) is the variable.
**Questions:**
1. **(A1) Cyclic**:
- A transformation is cyclic if there exists a vector such that its cyclic subspace (generated by that vector) equals the entire space.
2. **(A2) Irreducible**:
- A linear transformation is irreducible if there is no non-trivial invariant subspace that it leaves unchanged.
3. **(A3) Indecomposable**:
- A transformation is indecomposable if it cannot be written as a direct sum of two or more invariant subspaces.
