Answer:
The amplitude is 4 and the period is 2
Step-by-step explanation:
In the equation y = A sin (B x)
- A is the amplitude, where the amplitude is the height from highest to lowest points and divide the answer by 2
- The period is
, where the period is the distance from one peak to the next peak
∵ The equation is y = 4 sin(πФ)
- Compare it with form above
∴ A = 4 and B = π
∵ A is the amplitude
∴ The amplitude is 4
∵ Period =
∴ Period =
∴ Period = 2
∴ The period is 2
