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
