WebSep 16, 2024 · 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.

Suppose f : R → R is a function such that each of its first-order partial derivatives exist on R . This function takes a point x ∈ R as input and produces the vector f(x) ∈ R as output.
