[trigonometric graphs]use the following information to write an equation of the graph described: 7. sin; amp = 2, per = π, vertical shift = down 3.8. cos; amp = 1; per = π/4, phase shift = left π.explain.

7. y = 2 sin (2x) - 3

Step-by-step explanation:

The general form of a sine equation is: y = A sin (Bx - C) + D    where

7. Given:
