leitkurve-x^2+14x-45

Lösung

leitkurve

- x^{2} + 14 x - 45

Lösung

y = \frac{17}{4}

Schritte zur Lösung

Rewrite

y = - x^{2} + 14 x - 45

in the standard form

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

(h, k) = (7, 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

(7, 4)

y-coordinate

y = 4 - p

y = 4 - (- \frac{1}{4})

Fasse zusammen

y = \frac{17}{4}
