cubic
y=x³
A cubic is a polynomial function with the highest degree of three. It is also known as a third-degree polynomial. The general form of a cubic function is given as:
f(x) = ax^3 + bx^2 + cx + d
where a, b, c, and d are constants and x is the independent variable.
The graph of a cubic function is a smooth curve with one hump or one valley, depending on the sign of the leading coefficient. If the leading coefficient (a) is positive, the curve opens upwards, and if it is negative, the curve opens downwards.
Cubic functions have various practical applications, such as modeling the growth of organisms, measuring the volume of a box, predicting the trajectory of projectiles, and analyzing fluid dynamics. They are also widely used in engineering, physics, economics, and other fields of science.
