Function y is a function of cosine transformed by some operations, so cos can take values from interval <-1;1>, which means that this function can take values from interval <-7;-1>. The minimum value is -7. The graph will be very helpuf in this task to understand.
Answer:
A
Step-by-step explanation:
Taking the square root of both sides, you get

which simplifies to

The square root of 180 is approximately 13.42 and since it is the plus or minus square root, the answer is A, -13.42, 13.42.
Answer:
The answer is 7.
