In place of t, or theta, I'm going to utilize x instead. So the equation is -3*cos(x) = 1. Get everything to one side and we have -3*cos(x)-1 = 0
Let f(x) = -3*cos(x)-1. The goal is to find the root of f(x) in the interval [0, 2pi]
I'm using the program GeoGebra to get the task done of finding the roots. In this case, there are 2 roots and they are marked by the points A and B in the attachment shown
A = (1.91, 0)
B = (4.37, 0)
So the two solutions for theta are
theta = 1.91 radians
theta = 4.37 radians

The coordinates of the original quadrilateral are (1, 2), (4, 2), (1, 4), and (4, 4). After transformation, the new coordinates are (1, −2), (4, −2), (1, −4), and (4, −4). Thus, as we can see, the y coordinates of the original points have been multiplied by-1. This happens only when there is a reflection about the x axis.
Thus, the type of transformation in question here is reflection about the x axis.
