Name: Algebra 2 Part 2 Final Exam Directions: Answer the questions below. Make sure to show your work and justify all your answers. For a short time after a wave is created by wind, the height of the wave can be modeled using y = a sin 2 TC T ". where a is the amplitude and T is the period of the wave in seconds. 13. Write an equation for the given function given the amplitude, period, phase shift, and vertical shift. amplitude: 4, period - 41, phase shift = vertical shift = -2 14. Write an equation for the given function given the period, phase shift, and vertical shift. cotangent function. period - ", phase shift - - It,vertical shift = 2
