Image of Element under Mapping/Examples/Arbitrary Example 1

Example of Image of Element under Mapping

Let:

\(\ds A\)

\(=\)

\(\ds \set {a, b, c, d}\)

\(\ds B\)

\(=\)

\(\ds \set {w, x, y, z}\)

Let $f: A \to B$ be a mapping defined such that:

$\map f a = z$

Then $z$ is the image of $a$ under $f$.
