a polynomial function in a single variable where the highest exponent of the variable is 3
Graph of a cubic function with 3 real roots (where the curve crosses the horizontal axis—where y = 0). The case shown has two critical points. Here the function is f(x) = (x + 3x − 6x − 8)/4.
In mathematics, a cubic function is a function of the form
