Answer: The amplitude is 4.
Step-by-step explanation:
Given the form of the sine function:
Where is the amplitude,
is the period and "k" is the vertical shift of the wave.
You know that, in the sine function given ( ), you can identify the amplitude and the period. These are:
- The amplitude is:
- And the period is:
Therefore, the amplitude of is:
