6B - Cubed root function

The cubed root graph

The cubed root function has a general form:

• All cubed root graphs have the same shape, they are just transformed (dilated, reflected and translated) according to the values of the parameters a, n, h and k.

Introduction to the cubed root graph

Consider the following numbers and their cubed roots:

Table 1 - The cube root of perfect cubes.

If we plot these point on a set of axes we can see the shape of the cubed root graph:
