create a graph for these tasks

3. For the following sinusoidal functions, graph one period of every transformation from its base form, and describe each transformation. Be precise. (6 marks each) a. f(1:) = 3 - cos(45[$ 2 + 5 b. 9(3) 2 2.5 - sin(-3($ + 900)) 1 5. A sine function that has an amplitude of 16 units, a period of 5 units, a vertical displacement of 3 units up, and a phase shift of 2.5 units left. Graph this function and show each step. (5 marks}
