In this exploration, you have the chance to use what you have learned about trigonometric functions and their graphs by building a function that models a real periodic situation (a merrygoround). Watch the video “MerryGoRound.” (MerryGoRound descriptive transcript) pt. 1 Assume the camera is placed 6 feet from the center of the merrygoround and the diameter of the merrygoround is 6 feet. Build a trigonometric function that models the distance (feet) of the rider from the camera as a function of time (seconds). Be sure to use function notation to express your function model. pt 2. Draw the graph of your trigonometric function. Be sure to show labeled axes on your graph. pt 3. Identify the domain of your function. Explain what the domain has to do with the video you watched. pt 4. Identify the range of your function. Explain what the range has to do with the video you watched. pt 5. What is the period of your function? Explain what the period has to do with the video you watched. pt 6. What is the midline of the graph of your function? Explain what the midline has to do with the video you watched. video: https://players.brightcove.net/11262...=5556623829001 transcript: MerryGoRound Video—Descriptive Text [00:00] Words on the screen read “distance from camera,” and underneath that, “regular speed.” A man is shown climbing on top of a merrygoround at a playground. A timer on screen says ready, set, go, and then begins counting the seconds. [00:04] The man uses his foot to propel the merrygoround forward. If we pretend the merrygoround is a clock, he starts at 6:00. At 1 second he is at 12:00; at 2 seconds, 2:00; 3 seconds, 4:00; 4 seconds, 9:00. [00:11] At 7 seconds he is back around to 6:00. 7 seconds, 9:00; 8 seconds, 11:00; 9 seconds, 3:00, 10 seconds, 6:00; 11 seconds, 9:00. [00:16] At 12 seconds he reaches 12:00 and stops the merrygoround. [00:20] The video then rewinds and replays at half speed from the beginning.

At what height is the camera in relation to the man? Your transcript is incorrect.

I was not given that information, unfortunately.
