On the complex plane, the number 
is mapped onto the point with coordinates 
.
In other words, the x coordinate is the real part of the number, while the y coordinate is the complex part of the number.
Viceversa, if you start from a point 
, you can identify the number 
.
So, the endpoints of the diagonal are the points 
and 
. These are points A and C in the attached figure.
This means that points B and D have coordinates
So, the correspondant complex numbers are

Answer:
3
Step-by-step explanation:
it is the correct answer
Given that the directrix is at y = 4 and the focus is at (0, -4), then the vertex is at (h, k) = (0, 0).
p is the distance between the vertex and the focus and between the vertex and the directrix = 4 and since the focus is below the directrix, p is negative, i.e. p = -4
Equation of a parabola is given by (x - h)^2 = 4p(y - k)
Therefore, the required equation is (x - 0)^2 = 4(-4)(y - 0)
x^2 = -16y
y = -1/16 x^2
