Handling this question might be easier using the already derived equation for the simpler model of x=y^2. Taking this simple form as 4x=y^2 to get directrix and focus depends on knowing how the equation was formed from knowing directrix and focus.

is an equation of a parabola with p being distance from vertex to directrix and distance from vertex to focus. Your given equation is . The parabola is horizontal with a vertex (0,0). Focus is (0,1) and directrix is .
