The coordinates of the focus of the parabola y2 – x – 2y + 2 = 0

Given equation of the parabola is y2 - x - 2y + 2 = 0



y2 - 2y + 2 = x


y2 - 2y + 1 = x - 1


(y - 1)2 = (x - 1)


Comparing with the standard form of parabola (y - a)2 = 4b(x - c) we get,


4b = 1



The focus is (b + c, a) =


The correct option is A
