leitkurve y=x^2+12x+45

Lösung

leitkurve

y = x^{2} + 12 x + 45

Lösung

y = \frac{35}{4}

Schritte zur Lösung

Rewrite

y = x^{2} + 12 x + 45

in the standard form

4 \cdot \frac{1}{4} (y - 9) = (x - (- 6))^{2}

(h, k) = (- 6, 9), 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

(- 6, 9)

y-coordinate

y = 9 - p

y = 9 - \frac{1}{4}

Fasse zusammen

y = \frac{35}{4}
