Answer:
In mathematics, a cubic function is a function of the form f(x)=ax³+bx²+cx+d where the coefficients a, b, c, and d are complex numbers, and the variable x takes real values, and a ≠ 0. In other words, it is both a polynomial function of degree three, and a real function. In particular, the domain and the codomain are the set of the real numbers. Setting f(x) = 0 produces a cubic equation of the form ax³+bx²+cx+d=0, whose solutions are called roots of the function.
Step-by-step explanation:
Properties of the cubic function
One to three roots.
Two or zero extrema.
One inflection point.
Point symmetry about the inflection point.
The range is the set of real numbers.
