The facts on the card
The card carries these facts from its Wikipedia article.
- Similarly, an odd function is a function such that f = − f for every x in its domain.
- They are named for the parity of the powers of the power functions which satisfy each condition: the function f = x n is even if n is an even integer, and it is odd if n is an odd integer.
- Even functions are those real functions whose graph is self-symmetric with respect to the y-axis, and odd functions are those whose graph is self-symmetric with respect to the origin.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Even and odd functions article was read about 51,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 63 and blocks with 46: each hit it takes is cut by 18 %.
How to get Even and odd functions
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
