leitkurve t^2+2t-48

Lösung

leitkurve

t^{2} + 2 t - 48

Lösung

y = - \frac{197}{4}

Schritte zur Lösung

Rewrite

y = t^{2} + 2 t - 48

in the standard form

4 \cdot \frac{1}{4} (y - (- 49)) = (t - (- 1))^{2}

(h, k) = (- 1, - 49), 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, - 49)

y-coordinate

y = - 49 - p

y = - 49 - \frac{1}{4}

Fasse zusammen

y = - \frac{197}{4}
