A transformation of a given figure changes its size, position, or shape. Lines of reflection, angle measurements, and distances are used to describe transformations according to the type of transformation that occurred. Not only can you transform shapes and figures, but you can also transform functions. Piecewise functions can be transformed through the application of transformations to each piece individually. Different ways to transform functions are: horizontal and vertical translation, reflection across the x- and y-axis, and horizontal and vertical stretch/compression.
