Determine the coordinates of G and H
Since EFGH is a parallelogram, then:
D is the midpoint of EG and EF
For EG, we have:

Where x, y are the coordinates of G.
Multiply both sides by 2

By comparison:
==> 
==> 
So:

For FH, we have:

Where x, y are the coordinates of H.
Multiply both sides by 2

By comparison:
==> 
==> 
So:

In order for the curve to move upwards from left to right as shown the log and x values need to be negatives. The curved line crosses the x axis to the right of the origin, so there needs to be a positive value added to x.
The answer is d. F(x) = -4log(-x+4)
