nLab cubic function




In commutative rings

For a commutative ring RR, a cubic function is a function f:RRf \colon R \to R with elements aRa \in R, bRb \in R, cRc \in R, dRd \in R such that for all xRx \in R,

f(x)=ax 3+bx 2+cx+df(x) = a \cdot x^3 + b \cdot x^2 + c \cdot x + d

where x 2x^2 and x 3x^3 is the canonical square function and cube function? of the multiplicative monoid.
