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
