timed! answer quickly! (provide explanations if possible.)which function and domain could represent the given graph? a: f(x) = 1 – [x]; –3 < x < 3 b: f(x) = 1 + [x]; –3 ≤ x ≤ 3 c: f(x) = –[x]; –3 ≤ x ≤ 3 d: f(x) = [x]; –3 < x < 3

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d. what is the height of the tide after 93 hours?
