Question

A hotel manager recorded the percentage of rooms that were occupied each day over a period of 25 days. The data she collected is shown on the graph.The manager recognizes that the data approximates a transformation of the parent sine function, Y = sin(e).Which value is closest to the amplitude of the transformed function?

Answer 1

Amplitude = (maximum - minimum)/2

From the graph,

maximum = 70

minimum = 40

Amplitude = (70 - 40)/2 = 30/2

Amplitude = 15
