1) State the amplitude, period, phase shift, vertical shift and graph

See answers and explanations below (along with a visual graph)

Step-by-step explanation:

For the function :

Amplitude:

Period:

Phase shift:

Vertical shift:

Therefore, for :

Amplitude: , which is 2 units above and below the midline (see d)

Period: , so the cycle will repeat every 3π units

Phase shift: , or π units to the left

Vertical shift: , or 1 unit down

ιт ιѕ вє¢αυѕє:

6: 4= 3/2

18: 8= 9/4
