How do you use cubic function in real life?

Cubic functions are used in various real-life applications, such as modeling the volume of a cube, predicting the growth of certain biological organisms, or analyzing the behavior of certain physical systems. In engineering, cubic functions can be used to describe the relationship between variables in complex systems, such as fluid dynamics or structural mechanics. Additionally, cubic functions are often utilized in economics to model demand and supply curves, as well as in finance for analyzing investment returns over time.
