A) As you can see in the graph attached, the repeating pattern of the function is π, therefore the period is: Period=π The amplitude is: Amplitude=4-(-4)/2=8/2 Amplitude=4 b) The graph shows that the maximum values are (Where y=4): Maximum values: 0,π,2π The minimum values are (Where y=-4): Minimum values:π/2,3π/2 The zeros are:π/4,3π/4,5π/4,7π/4
