Answer:
The amplitude is
Step-by-step explanation:
Let f(x) be a sinusoid function that has the following format:
Then b is the amplitude of the function
h is the vertical displacement of the wave
s is the phase angle
is the period.
In this problem
Then
Therefore the amplitude of the function is
The amplitude is a measure of the vertical size of the sinx wave
