A polar function is given by 𝑟=𝑓𝜃=3cos𝜃. A rectangular graph of 𝑓𝜃 is given below. As 𝜃 increases on the interval 𝜋2<𝜃<𝜋, which of the following is true about the points on the polar graph of 𝑟=𝑓𝜃 in the 𝑥𝑦-plane?
(A) The points on the polar graph are above the 𝑥-axis and are getting closer to the origin.
(B) The points on the polar graph are below the 𝑥-axis and are getting farther from the origin.
(C) The points on the polar graph are below the 𝑥-axis and are getting closer to the origin.
(D) The points on the polar graph are above the 𝑥-axis and are getting farther from the origin.
