A sinusoidal wave is shown. This wave has been transformed by a vertical dilation (stretch) and a vertical translation (shift). [br][br]Find an equation for the wave and enter it in the input box at the bottom. [b]Your goal[/b]: find an equation to match the graph on the first try. You will know you are right because the new graph (thin black line) will exactly match the red graph.[br][br]Then try again. Press CTRL-R or click the “Reset” icon in the upper right for a new graph. Once you are good with vertical transformations, move on to other transformations at [url]http://www.geogebratube.org/user/profile/id/905[/url].
