Assume f(x) = g(x). which of the following two functions may be used to represent the function 3x = x – 4? * 1 point a) f(x) = 3x, g(x) = x – 4 b) f(x) = x – 7, g(x) = x – 4/3 c) f(x) = 3x, g(x) = 3x d) f(x) = 7, g(x) = 3x

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).

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?
