WebTo show that a function is not onto, all we need is to find an element y ∈ B, and show that no x -value from A would satisfy f(x) = y. In addition to finding images & preimages of elements, we also find images & preimages of sets. Given a function f: A → B, the image of C ⊆ A is defined as f(C) = {f(x) ∣ x ∈ C} . Web24 de ago. de 2015 · Yes, you are correct. We can "make" a linear transformation onto by restricting the codomain to the image of the transformation. Your question is really about functions in general and not related to linear algebra. Any function should be thought of as a triple ( f, X, Y) which is normally denoted by f: X → Y.
