Write a possible equation for a polynomial whose graph has the following horizontal intercepts. Check your equation using graphing technology. (x, y) [f(x) = y]
1. (4, 0) f(x)=(x-4)
2. (0, 0) and (4, 0)
3. (-2, 0), (0, 0) and (4, 0)
4. (-4, 0), (0, 0), and (2, 0)
5. (-5, 0), (1/2, 0), and (3, 0)

Match each inequality to the number line that represents its solution

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?

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?
