Step-by-step explanation:
Discriminant : k² - 4(12)(27) < 0
So k² - 1296 < 0, -36 < k < 36.
The answer to this would be 4(w-4)
Use the pic and solve the COS x-sin x/COS x+ sin x part
comment if there's something u don't understand
In 180 degree rotation, magnitude remains same, and sign of the coordinate changes. So, the coordinates of Pre-image would be: Z (-9, -2)
In short, Your Answer would be: Option B
Hope this helps!
