    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 ... (6x)^3 - (3y)^3

    factoring pattern is ... a^3 - b^3 = (a-b)(a^2 + ab + b^2)

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

    any more points? would be nice to have at least one more.
