Find the difference: 0.151 − 0.028

amplitude = 6.5

Step-by-step explanation:

The amplitude of a function is the maximum displacement from the from a fixed point or from the origin.

From the graph, you take the initial position of the object from the broken red line which is equal to 3.3 at the Y axis.

The peak or the maximum value = 9.8

Amplitude = 9.8 - 3.3 = 6.5

The maximum displacement is at Y axis
