## Transformations of graphs

Click this button to open an xFunctions window. The
pop-up menu at the top of the screen contains several examples
that show the effect of various stretching and sliding
transformations on a function.

## Transformed Sine Functions

Click this button to open a window that shows a sine function with parameters A, B, C, D representing horizontal and vertical
stretches and slides. The values of the parameters can be controlled with sliders that appear below the graph.
A is the *amplitude*, B is the *frequency*, C is the *phase*,
and D is the vertical offset.
