Find the matrices of the linear transformations from $\mathbb{R}^{3}$ to $\mathbb{R}^{3}$ given in Exercises 19 through $23 .$ Some of these transformations have not been formally defined in the text. Use common sense. You may assume that all these transformations are linear. The reflection about the plane $y=z$

Key Concepts

Linear Transformation

A linear transformation is a function between vector spaces that preserves vector addition and scalar multiplication. In Euclidean spaces such as ?³, common examples include rotations, reflections, and projections, each having predictable effects on the structure of the space.

Matrix Representation of a Linear Transformation

Every linear transformation can be represented by a matrix once bases for the domain and codomain are fixed. This matrix encapsulates the transformation’s action on the basis vectors, thereby allowing the transformation to be applied to any vector via matrix multiplication.

Reflection Transformation

A reflection is a linear transformation that 'flips' vectors about a specified subspace (like a line in ?² or a plane in ?³). In a reflection, points on the subspace remain fixed while points off the subspace are mapped symmetrically across it. The resulting matrix is often orthogonal and symmetric, reflecting the isometric property of the transformation.
