what is the amplitude of the function shown on the graph below?

Answer:
amplitude of the wave is 2.
Step-by-step explanation:
Given : Figure of wave .
To find : what is the amplitude of the function
Solution : We have given a figure of wave
Amplitude : The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position.
We can see from the given figure that wave is maximum at up to y = 2
So, the amplitude of the wave is 2.
Therefore, amplitude of the wave is 2.
