Answer
1.2
Work Step by Step
The amplitude is half the difference between the maximum and minimum values on the graph.
According to the graph,
Maximum value= 2.6 feet
Minimum value= 0.2 feet
Therefore,
Amplitude$=\frac{1}{2}$(Max-Min)
Amplitude$=\frac{1}{2}(2.6-0.2)$
Amplitude$=\frac{1}{2}(2.4)$
Amplitude$=1.2$
