Math Help - Factoring and transformations.

I dont know how I would solve these questions.

1. Factor 216x^3-27y^3
The answer is suppose to be (6x-3y)(36^2+18xy+9y2)

2.Describe the transformations that were applied to the parents function y=x^3 to create the following graph.

The points of the graph are (-1,-3) and (0,-5)

difference of cubes ...

factoring pattern is ...
