Write an equation for a function with theGiven characteristics. A sine curve with a period of 8x, an amplitude of 3, a left phase shift of π/2, and a vertical translation down 2 units.
a) y = -2 - 3sin(2πx/8 - π/2)
b) y = -2 + 3sin(2πx/8 - π/2)
c) y = -2 + 3sin(8πx - π/2)
d) y = -2 - 3sin(8πx - π/2)
