What sine function represents an amplitude of 1, a period of 2pi, a horizontal shift of our, and a vertical shift of -4

ANSWER

EXPLANATION

The basic sine function is

The transformed sine function has equation

where a=1 is the amplitude

2π/b=2π is the period

c/b= 4 is the horizontal shift 4 units left.

d=-4 is a downward vertical shift of 4 units.

The required sine function is:

(-5,-28)
