X = 1/4y^2 The focus of the parabola is: (0, 1) (1, 0) (0, - 1)

x = 1/4y^2

Vertex form is written as x = a (y-k) ^2 + h

Using the given equation determine the values for a, h and k:

a = 1/4, k = 0, h = 0

The vertex of a parabola is (h, k) = (0,0)

Find the distance form the vertex to a focus using the formula 1/4a

from above we know a = 1/4 so now you have:

1 / (4 (1/4))

Simplify

1 / (4 (1/4)) = 1

p = 1

The focus is (h+p, k)

Using the values you have:

Focus = (0+1, 0)

= (1,0)
