leitkurve y=-1/14 x^2+2

Lösung

leitkurve

y = - \frac{1}{14} x^{2} + 2

Lösung

y = \frac{11}{2}

Schritte zur Lösung

Rewrite

y = - \frac{1}{14} x^{2} + 2

in the standard form:

4 (- \frac{7}{2}) (y - 2) = (x - 0)^{2}

(h, k) = (0, 2), p = - \frac{7}{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

(0, 2)

y-coordinate

y = 2 - p

y = 2 - (- \frac{7}{2})

Fasse zusammen

y = \frac{11}{2}
