Answer:

2cos(3x)

Step-by-step explanation:

If the function were just cos(x), then the second peak would happen at 2π.  Instead though, it happen 2π / 3.   That means that the coefficient of x must be 3.

At zero, we see a peak of the curve, so we're dealing with a cos function, that peak happens at (0, 2), so the coefficient of the function is 2.

That tells us that the function graphed here must be 2cos(3x).

The correct answer is option A which is the equation of the given graph is y = 2cos(3x)

What is a graph?

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

If the function were just cos(x), then the second peak would happen at 2π.  Instead, though, it happens 2π / 3.   That means that the coefficient of x must be 3.

At zero, we see a peak of the curve, so we're dealing with a cos function, that peak happens at (0, 2), so the coefficient of the function is 2.

Therefore the correct answer is option A which is the equation of the given graph is y = 2cos(3x)
