Step-by-step explanation:
The graph in the attachment is a quadratic function whose vertex is in the fourth quadrant.
The coordinates of a point in the fourth quadrant is of the form 
Considering the options, the vertex must have coordinates
and
.
The quadratic function in vertex form is written as;

Therefore the equation of the quadratic function is;

The correct answer is option D
Using the quadratic equation we get:

Factoring out 2 we get

Factoring out the imaginary number:

So b.
