leitkurve y=x^2-2x-15

Lösung

leitkurve

y = x^{2} - 2 x - 15

Lösung

y = - \frac{65}{4}

Schritte zur Lösung

Rewrite

y = x^{2} - 2 x - 15

in the standard form

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

(h, k) = (1, - 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

(1, - 16)

y-coordinate

y = - 16 - p

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

Fasse zusammen

y = - \frac{65}{4}
