Answer:

A.
x = 4\cdot (y-1)^(2)-2

Explanation:

From the image attached below statement we understand that a parabola with a horizontal axis of symmetry and whose vertex is centered at
V(x,y) = (h,k) is defined by the following expression:


x-h = C\cdot (y-k)^(2) (1)

Where
C is the parabola factor, when
C > 0, the parabola is oriented in the +x direction, otherwise is oriented in the -x direction. Hence, we may conclude that equation of the parabola is of the form:


x+2 = C\cdot (y-1)^(2)


x = C\cdot (y-1)^(2)-2, where
C > 0

The correct answer is A.
