This category contains examples of Preimage of Mapping.
The preimage of $f$ is defined as:
- $\Preimg f := \set {s \in S: \exists t \in T: f \paren s = t}$
That is:
- $\Preimg f := f^{-1} \sqbrk T$
where $f^{-1} \sqbrk T$ is the image of $T$ under $f^{-1}$.
In this context, $f^{-1} \subseteq T \times S$ is the the inverse of $f$.
