leitkurve y=-1/4 (x^2-14x+13)

Lösung

leitkurve

y = - \frac{1}{4} (x^{2} - 14 x + 13)

Lösung

y = 10

Schritte zur Lösung

Rewrite

y = - \frac{1}{4} (x^{2} - 14 x + 13)

in the standard form

4 (- 1) (y - 9) = (x - 7)^{2}

(h, k) = (7, 9), p = - 1

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

(7, 9)

y-coordinate

y = 9 - p

y = 9 - (- 1)

Fasse zusammen

y = 10
