leitkurve x^2+5x-7

Lösung

leitkurve

x^{2} + 5 x - 7

Lösung

y = - \frac{27}{2}

Schritte zur Lösung

Rewrite

y = x^{2} + 5 x - 7

in the standard form

4 \cdot \frac{1}{4} (y - (- \frac{53}{4})) = (x - (- \frac{5}{2}))^{2}

(h, k) = (- \frac{5}{2}, - \frac{53}{4}), 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

(- \frac{5}{2}, - \frac{53}{4})

y-coordinate

y = - \frac{53}{4} - p

y = - \frac{53}{4} - \frac{1}{4}

Fasse zusammen

y = - \frac{27}{2}
