## 2.2 Cubic Function and Higher Power Polynomials

#### Cubic Functions Basics

- Cubic functions has the general form

f(x)=a x^{3}+b x^{2}+c x+d, where a,\ b,\ c,\ d \in R,\ a \neq 0

- Cubic functions cannot be fully understood without the use of calculus. Therefore, it will be revisited in A3 – Calculus.

- The ‘shapes’ of cubic graphs vary. Below is a gallery of cubic graphs, demonstrating the variety of ‘shapes’ that are possible.
