Answer:
The correct answer is B.
Step-by-step explanation:
Any point can be represented in polar form by using the notation:
(1)
And any polar function must satisfy the following definition:

Let
, where
is the radial distance of any point of the curve from origin and
is the direction of any point of the curve with respect to +x semiaxis, measured in radians.
Finally, we proceed to graph the function with the help of a graphing tool and attach the result.
Besides, we must remember that cosine is a bounded function, which means that domain and range in rectangular coordinates are represented by:
, ![Ran\{f\} = [-4,4]](https://tex.z-dn.net/?f=Ran%5C%7Bf%5C%7D%20%3D%20%5B-4%2C4%5D)
Then, the correct answer is B.
