Question

Identify the period and amplitude of the function shown in the graph.see imagea)Period: 2; Amplitude: 5b) Period: 2; Amplitude: 2.5c) Period: 2.5; Amplitude: 2d) Period: 5; Amplitude: 2

Answer 1

Part a

Find out the Amplitude

Remember that

The Amplitude is the height from the centerline to the peak

looking at the graph

max=4

min=-1

so

centerline=(4+1)/2=2.5

The amplitude is 2.5

Part b

Find out the Period

The Period goes from one peak to the next

so

the distance between two peaks is 3-1=2

Period =2

therefore

the answer is option B
