The x-intercept is 1, and (x, y) = (- 2, 3) a point on the line

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

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?

Which graph has figures that can undergo a similarity transformation to justify that they are similar? (obviously not the third one)
