leitkurve y= 1/2 x^2+9x+8

Lösung

leitkurve

y = \frac{1}{2} x^{2} + 9 x + 8

Lösung

y = - 33

Schritte zur Lösung

Rewrite

y = \frac{1}{2} x^{2} + 9 x + 8

in the standard form

4 \cdot \frac{1}{2} (y - (- \frac{65}{2})) = (x - (- 9))^{2}

(h, k) = (- 9, - \frac{65}{2}), p = \frac{1}{2}

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

(- 9, - \frac{65}{2})

y-coordinate

y = - \frac{65}{2} - p

y = - \frac{65}{2} - \frac{1}{2}

Fasse zusammen

y = - 33
