The musical note E can be modeled by the function, y = asin(1320πx), where a = 1 and x is the time in seconds. Playing note E on your computer, you notice that it is not loud enough to be heard across the room. What change can you make to the function to make note E louder than the original? Let a < 0. Let a > 0. Let a > 0 and a < 1. Let a > 1 or a < –1.
