The **cubic function** is a function that is given by a polynomial of the third degree, and has the form of **y=ax^3+bx^2+cx+d**, where **a, b, c, d** are some numbers, **(a≠0)**.

The **graph of a cubic function is a cubic parabola** whose vertex is at (0;0).

The scope and scope of a function are a set of real numbers. The function is incremental.

*Special case: y=ax^3, (а≠0).* Located in I and III quarters at a>0, in II and IV quarters at a<0.

The cubic function of the form **y=a(x-m)^3** shifts along the x-axis when the **m** coefficient changes. The cubic function of the form **y=ax^3+n** shifts along the Y axis when the coefficient of **n** changes.

**у=-x^3**

**у=1/2x^3**

**у=x^3+2**

у=2x^3+x^2+6x+7
