Answer: The correct option is (C). (2, -5).
Step-by-step explanation: The given function is

The vertex form of the function g(x) is 
We know that if the vertex form of a function f(x) is written as

then its vertex is (h, k).
So, from equation (i), we can say that the vertex of function g(x) is
(2, -5).
Thus, (C) is the correct option.
It would be negative six.
Area of a parallelogram = b*h (base*height)
b= 12cm
h= 18cm
Therefore:
= 12*18 cm
Area of the parallelogram = <u><em>216cm</em></u>
