That's it. The 4 refers to the amplitude
- 00:22
of the sine curve or how high and low the graph can go.
- 00:25
When we look at all the answer choices only one actually has this
- 00:29
amplitude of 4. Big high up thingy here and the low thingy there. That's amplitude.
- 00:36
So it's option C.
- 00:37
As further confirmation options C is a normal sine curve
- 00:41
besides from its amplitude. So that's it... piece a cake. It's option C.
