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

The temperature in Calgary, over the course of a year, can be approximated using thesinusoidal function
T(x) =  16.11sin(0.51x −1.75)+9.14
where T represents thetemperature in °C and x represents the number of the month, where January 1st is monthnumber 1, February 1st is month number 2, etc.
The temperature in Calgary on July 1st is

• 24.8⁰C
• 20.8⁰C
• 25.3⁰C
• 16.1⁰C
