I've asked this before, but when I was looking at my notes, I saw that graph # 4 was marked as true in this question (attachment) and it was the one graph I thought had only 2 units for the amplitude. Is graph #4 the answer still?

@terenzreignz I asked you this question before, but I was hoping you can take a look again and tell me if my doubt in my answer is just silly lol :p

anonymous · Answer

it's graph 4, amplitude is the magnitude of change between oscillation . in other words it's the extrema
