ng information to Four sound waves are modelled by the following graphs of periodic functions. The portion of each graph on the domain 0 s x S 360 is shown below. Graph 1 Graph 2 Graph 3 Graph 4 270- 315- 90' 135 180 225" 270' 315 360 The louder a sound is, the greater the amplitude of the wave. The graphs that represent the sound waves shown above in order from the loudest sound to the quietest sound are and
