What is the equation of the graph below?

On a coordinate plane, a curve crosses the y-axis at (0, negative 1). It has a minimum of negative 1 and a maximum of 1. It goes through 1 cycle at 2 pi.
y = cosine (x + StartFraction pi Over 2 EndFraction)
y = cosine (x + 2 pi) y = cosine (x + StartFraction pi Over 3 EndFraction)
y = cosine (x + pi)

Step-by-step explanation:

Remember that the cosine function has a period of 2π.

Now, the parental function is , which has y-intercept at y = 1, and x-intercept at π/2.

Notice that the function showed in the graph attached has y-intercept at y = -1 and x-intercept at π/2. This indicates that the function has been moved leftwards π units.

Therefore, the function that belongs to this graph is

D
