Answer:
1.5
Step-by-step explanation:
Amplitude: the height from the center line to the maximum or minimum point.
We can either determine the center line, or we can measure the height between the max to min points and divide that by 2.
From inspection of the graph, the max points are at y = -0.5 and the min points at y = -3.5
Therefore, the distance between them = -0.5 - -3.5 = 3
Divide by 2 = 3/2 = 1.5
Therefore, the amplitude = 1.5
