For the past three years, the manager of a shop has observed that revenue reaches a high of about S60,000 in December and a low of about $10,000 in June, and that a graph of the revenue looks like a sinusoid If the months are numbered 1 through 36 with 1 corresponding to January, then what are the period, amplitude, and phase shift for this sinusoid when its equation is written in the form y = A sin [B(x- C)]+ D? What is the vertical translation? Write a formula for the curve and find the approximate revenue for March.

graph the function “y = -1 cos (4x + (4π/3)) + 2” a) before phase shift, b) after phase shift neatly. Show all 4 quadrant and 5 points in a) and b). Hello i know how to graph with a phase shift but how do i graph this without a phase shift?

Suppose y = 37 Cos (-4t + 5) + 9. In your answers, enter 'pi' for T. (a) The amplitude of the graph is (b) The period of the graph is (c) The phase (horizontal shift) of the graph is (d) The midline (vertical shift) of the graph is y

1. One cycle of a sine function begins at x = 3 and ends at x = a. Determine the period of the function. b. Determine the phase shift of the function. c. Write the equation of the function in the form y = sin k(x - d)
