Fit Graph: Sinusoid_1, Vertical Dilation

A sinusoidal wave is shown. This wave has been transformed by a vertical dilation (stretch). Find an equation for the wave and enter it in the input box at the bottom. Your goal: 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. 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 dilations, move on to other transformations at
