MCR3U1 CHAPTER 6 ASSIGNMENT 16 NAME: ______________________ 1 1. Without graphing, determine the amplitude, period, domain, and range of the function y = 1.7 cos x 3 . 5 2. Amplitude = __________ Period: _________ (SHOW WORK) Domain: __________________ Range: _______________________ /3 Felix and Alex ride the Ferris wheel together at the Markham Fair, which has a diameter of 15 m and a speed of 3.75 km/h. Draw a graph that shows Felix' and Alex' height above ground as they ride the Ferris wheel for 1 1 2 minutes if the Ferris Wheel is 2 m off the ground and the starting position is from the lowest point. (HINT: leave x-axis in terms of ) /5 3. Graph the function = 4 3 ( 90 ) 2 for 0 300 . (Show work.) /4 4. Determine the equation of the sinusoidal function that is modelled by the following graph by a cosine function. Then, give the equation of the sinusoidal function that is modelled by the following graph by a sine function. NO REFLECTIONS!
