Linear transformation examples.

Definition 5.5.2: Onto. Let T: Rn ↦ Rm be a linear transformation. Then T is called onto if whenever →x2 ∈ Rm there exists →x1 ∈ Rn such that T(→x1) = →x2. We often call a linear transformation which is one-to-one an injection. Similarly, a linear transformation which is onto is often called a surjection.A linear transformation preserves linear relationships between variables. Therefore, the correlation between x and y would be unchanged after a linear transformation. Examples of a linear transformation to variable x would be multiplying x by a constant, dividing x by a constant, or adding a constant to x .Definition 7.3.1: Equal Transformations.
