Suppose that the linear transformations $T_{1}: P_{2} \rightarrow P_{2}$ and $T_{2}: P_{2} \rightarrow P_{3}$ are given by the formulas $T_{1}(p(x))=p(x+1)$
and $T_{2}(p(x))=x p(x) .$ Find $\left(T_{2} \circ T_{1}\right)\left(a_{0}+a_{1} x+a_{2} x^{2}\right)$.

Key Concepts

Multiplication by a Variable

Multiplying a polynomial by a variable, such as multiplying by x, is an operation that increases the degree of the polynomial by one. This type of transformation is important for understanding how linear operators can act on polynomial spaces, altering their structure while still preserving the framework of a vector space.

Linear Transformation

A linear transformation is a mapping between vector spaces that preserves the operations of vector addition and scalar multiplication. This concept is crucial in linear algebra as it provides a framework to study and understand how different spaces and their elements can be systematically related while maintaining the underlying linear structure.

Polynomial Spaces

Polynomial spaces, such as P? and P?, are examples of finite-dimensional vector spaces whose elements are polynomials of a bounded degree. They serve as fundamental examples in linear algebra and functional analysis, providing a setting for understanding vector space properties, bases, and dimensionality.

Composition of Transformations

The composition of transformations involves applying one linear transformation after another. This operation is significant because it provides a method to combine multiple transformations into a single mapping, allowing for complex operations to be expressed concisely and studied through the properties of linear operators.

Translation of Variable

Translation of a variable in a polynomial, such as replacing x with (x+1), is a specific type of transformation that modifies the argument of the polynomial. This concept helps illustrate how changing the input of a function affects its output and is a useful technique in various areas of mathematics, including signal processing and differential equations.
