Work Step by Step

The amplitude of a periodic function is half the difference between its maximum and minimum values. According to the graph, the maximum value is 8 while the minimum value is 4. Therefore, the amplitude is: Amplitude$=\frac{1}{2}$(Max-Min) Amplitude$=\frac{1}{2}(8-4)$ Amplitude$=\frac{1}{2}(4)$ Amplitude$=2$
