Let us summarize and consolidate the concept related to functions using an 'egg' diagram:
<div class="content-block"><figure class="question-figure aligncenter" style="text-align: center;"><img src="https://vocwkpgapvksartxhhor.supabase.co/storage/v1/object/public/question-images/pasted/1770376802411-azxwokjkpqq.png" style="max-width: min(400px, 100%); height: auto; display: block;" alt="Egg diagram representing a function mapping from domain A to codomain B" class="aligncenter custom-width" /></figure></div>
\(\mathrm{f}\): the name of the function
\(\mathrm{f}(x)\): the image of \(x\) under \(\mathrm{f}\)
\(A\): the domain of \(\mathrm{f}\), also denoted by \(D_f\)
\(B\): the codomain of \(\mathrm{f}\), we do not have a notation for this one.
