To find:The amplitude of a graph.
The amplitude of the graph is - 4.
Given data:
The graph of the function is shown in Fig.1.
Method/Formula used:
Amplitude of a periodic function is the maximum distance from the mean position. The amplitude of function
Calculations:
The graph of the function is shifted below the x-axis, therefore the periodic function corresponding to the graph given in Fig.1 is has the form,
The point
Substitute
Also, the point
Substitute
Equating B from the results (2) and (3),
Therefore, the amplitude of the graph is - 4.
