The facts on the card
The card carries these facts from its Wikipedia article.
- It is sometimes denoted by dom or dom f, where f is the function.
- In layman's terms, the domain of a function can generally be thought of as "what x can be".
- More precisely, given a function f : X → Y, the domain of f is X. In modern mathematical language, the domain is part of the definition of a function rather than a property of it.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Domain of a function article was read about 59,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 53 and blocks with 21: each hit it takes is cut by 8 %.
