Best ResponseYou've already chosen the best response.0Amplitude is half of the distance between the highest lowest points. The top and bottom points are 3 and 5, respectively. The distance between is 8, so the amplitude is half of 8, or 4.

Best ResponseYou've already chosen the best response.0First, we have to determine what the other 2 are. And second, B says that the amplitude is 8, so it can't be B.

Best ResponseYou've already chosen the best response.0Let's figure out what the period is. The period is the distance between the point on any wave and the same point on another wave. Kinda complicated way to say it, so a simpler way is just the distance between the tops of the waves. What is the horizontal difference between the top of two of the waves?

Best ResponseYou've already chosen the best response.02 what? There's something after the 2.

Best ResponseYou've already chosen the best response.0Yeah, it's \(2\pi\) So it has amplitude of 4 and period of \(2\pi\). Which choice is that?
