Transformation of Graphs

Transformation of a graph means moving or altering the graph's shape or position. The procedure for transforming the graph of one algebraic function is applicable to the other algebraic and trignometric functions.

In algebra there is a group of commonly used functions called parent functions and most graphs are either transformation of these functions or a combination of them.
They are:
Lets work with the cubic function y = x3 The graph of the cubic function is:
