leitkurve y=x^2-8x

Lösung

leitkurve

y = x^{2} - 8 x

Lösung

y = - \frac{65}{4}

Schritte zur Lösung

Rewrite

y = x^{2} - 8 x

in the standard form

4 \cdot \frac{1}{4} (y - (- 16)) = (x - 4)^{2}

(h, k) = (4, - 16), p = \frac{1}{4}

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

- p

from the center

(4, - 16)

y-coordinate

y = - 16 - p

y = - 16 - \frac{1}{4}

Fasse zusammen

y = - \frac{65}{4}
