x=y^2-2y

Solution

x = y^{2} - 2 y

Solution

(h, k) = (- 1, 1), p = \frac{1}{4}

Solution steps

x = y^{2} - 2 y

Rewrite

x = y^{2} - 2 y

in the standard form

4 \cdot \frac{1}{4} (x - (- 1)) = (y - 1)^{2}

Therefore parabola properties are:

(h, k) = (- 1, 1), p = \frac{1}{4}

Popular Examples

foci y^2=-4/5 (x-2)foci

y^{2} = - \frac{4}{5} (x - 2)

x^2-4y^2-20x-64y-172=0

x^{2} - 4 y^{2} - 20 x - 64 y - 172 = 0

9x^2+4y^2-18x+8y-23=0

9 x^{2} + 4 y^{2} - 18 x + 8 y - 23 = 0

25 x^{2} + 4 y^{2} = 100

directrix y=-2x^2-2x-2 directrix

y = - 2 x^{2} - 2 x - 2
