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

Gemiola [76]

Answer:

C.) y is greater than or equal to -6

Step-by-step explanation:

The range are all the set of y-values that are plotted on the vertical axis (y-axis).

The range starts from -6 and above. Which is y ≥ -6

Therefore, range of the function is said to be:

C.) y is greater than or equal to -6
