Cubic function, an Uncommon card
In mathematics, a cubic function is a function of the form f = a x 3 + b x 2 + c x + d, with a ≠ 0 , that is, a polynomial function of degree three.

Cubic function quiz: 3 questions
Three questions on the Cubic function card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Setting f = 0 produces a cubic equation of the form a x 3 + b x 2 + c x + d = 0, whose ______ are called roots of the function.
Answer
solutions. Setting f = 0 produces a cubic equation of the form a x 3 + b x 2 + c x + d = 0, whose solutions are called roots of the function. From the Cubic function article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
Snellen chart. Snellen chart 260,000 · Coulomb 170,000 · BMW B38 engine 46,000 · Cubic function 33,000 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- In many texts, the coefficients a, b, c, and d are supposed to be real numbers, and the function is considered as a real function that maps real numbers to real numbers or as a complex function that maps complex numbers to complex numbers.
- In other cases, the coefficients may be complex numbers, and the function is a complex function that has the set of the complex numbers as its codomain, even when the domain is restricted to the real numbers.
- Setting f = 0 produces a cubic equation of the form a x 3 + b x 2 + c x + d = 0, whose solutions are called roots of the function.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cubic function article was read about 33,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 58 and blocks with 30: each hit it takes is cut by 12 %.
How to get Cubic 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.
