leitkurve 3-x^2

Lösung

leitkurve

3 - x^{2}

Lösung

y = \frac{13}{4}

Schritte zur Lösung

Rewrite

y = 3 - x^{2}

in the standard form:

4 (- \frac{1}{4}) (y - 3) = (x - 0)^{2}

(h, k) = (0, 3), 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

(0, 3)

y-coordinate

y = 3 - p

y = 3 - (- \frac{1}{4})

Fasse zusammen

y = \frac{13}{4}
