directrix 2y^2-44x=0

directrix

2 y^{2} - 44 x = 0

x = - \frac{11}{2}

Solution steps

Rewrite

2 y^{2} - 44 x = 0

in the standard form:

4 \cdot \frac{11}{2} (x - 0) = (y - 0)^{2}

(h, k) = (0, 0), p = \frac{11}{2}

Parabola is symmetric around the x-axis and so the directrix is a line parallel to the y-axis, a distance

- p

from the center

(0, 0)

x-coordinate

x = 0 - p

x = 0 - \frac{11}{2}

Refine

x = - \frac{11}{2}

x = - \frac{3}{8} (y - 2)^{2} - 1

(y + 12)^{2} = 9 (x - 9)

0.5 x^{2} + 2

y = - 2 + x^{2}

y^{2} + 4 x + 1 = 0
