leitkurve x=y^2-y-42

Lösung

leitkurve

x = y^{2} - y - 42

Lösung

x = - \frac{85}{2}

Schritte zur Lösung

Rewrite

x = y^{2} - y - 42

in the standard form

4 \cdot \frac{1}{4} (x - (- \frac{169}{4})) = (y - \frac{1}{2})^{2}

(h, k) = (- \frac{169}{4}, \frac{1}{2}), p = \frac{1}{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

(- \frac{169}{4}, \frac{1}{2})

x-coordinate

x = - \frac{169}{4} - p

x = - \frac{169}{4} - \frac{1}{4}

Fasse zusammen

x = - \frac{85}{2}
