The function is defined only if
. So, the leftmost point is
, and we have

So, the first point is 
The three additional points seem arbitrary, so let's choose
. We have:

So, the second point is 

So, the third point is 

So, the fourth point is 
A,C, and D are in quadrant 3 and C is in quadrant 1
-1 is the answer to your question
Pretty sure it’s 16TXI, hope this helps!
