x^2=-4y

Solution

x^{2} = - 4 y

Solution

(h, k) = (0, 0), p = - 1

Solution steps

x^{2} = - 4 y

Rewrite

x^{2} = - 4 y

in the standard form:

4 (- 1) (y - 0) = (x - 0)^{2}

Therefore parabola properties are:

(h, k) = (0, 0), p = - 1

Popular Examples

eccentricity (x^2}{25}+\frac{y^2)/9 =1 eccentricity

\frac{x ^{2}}{25} + \frac{y ^{2}}{9} = 1

x = y^{2} - 4

foci ((x-5)^2)/4+((y+3)^2)/(16)=1 foci

\frac{( x - 5 ) ^{2}}{4} + \frac{( y + 3 ) ^{2}}{16} = 1

(x - 2)^{2} = 8 y

vertices y=2-x-2x^2 vertices

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