leitkurve y^2=-7x

Lösung

leitkurve

y^{2} = - 7 x

Lösung

x = \frac{7}{4}

Schritte zur Lösung

Rewrite

y^{2} = - 7 x

in the standard form:

4 (- \frac{7}{4}) (x - 0) = (y - 0)^{2}

(h, k) = (0, 0), p = - \frac{7}{4}

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{7}{4})

Fasse zusammen

x = \frac{7}{4}
