The facts on the card
The card carries these facts from its Wikipedia article.
- The expression a x 2 + b x + c , especially when treated as an object in itself rather than as a function, is a quadratic polynomial, a polynomial of degree two.
- In elementary mathematics a polynomial and its associated polynomial function are rarely distinguished and the terms quadratic function and quadratic polynomial are nearly synonymous and often abbreviated as quadratic.
- The graph of a real single-variable quadratic function is a parabola.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Quadratic function article was read about 47,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 62 and blocks with 47: each hit it takes is cut by 19 %.
How to get Quadratic function
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.
