Linear transformations are most commonly written in terms of matrix …A linear transformation A: V → W A: V → W is a map between vector spaces V V and W W such that for any two vectors v1,v2 ∈ V v 1, v 2 ∈ V, A(λv1) = λA(v1). A ( λ v 1) = λ A ( v 1). In other words a linear transformation is a map between vector spaces that respects the linear structure of both vector spaces.L(x + v) = L(x) + L(v) L ( x + v) = L ( x) + L ( v) Meaning you can add the vectors and then transform them or you can transform them individually and the sum should be the same.

Example 3.5.3: An invertible matrix.And I think you get the idea when someone says one-to-one. Well, if two x's here get mapped to the same y, or three get mapped to the same y, this would mean that we're not dealing with an injective or a one-to-one function. So that's all it means.
