• Black
• Blue
• Red

what is the amplitude of y=7sin(3x)-2

• 7
• -2
• 3
• 6

what is the Period of y=7sin(3x)-2

A Ferris wheel has a diameter of 38 ft. The bottom of the Ferris wheel is 3 ft. off the ground.

What would be the amplitude of the sinusoidal function representing this scenario?

• 41

• 35

• 22

• 19

If the Ferris wheel is placed on a stand 2 m higher lifting it further from the ground, and no other changes are made, the equation
y = asin(bx +c)+d
would be changed by

• increasing the amplitude of the graph by 2
• increasing the period of the graph by 2
• shifting the graph 2 units right
• shifting the midline 2 units up
