leitkurve+(x-1)^2+2

Lösung

leitkurve

+ (x - 1)^{2} + 2

Lösung

y = \frac{7}{4}

Schritte zur Lösung

Rewrite

y = (x - 1)^{2} + 2

in the standard form:

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

(h, k) = (1, 2), 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

(1, 2)

y-coordinate

y = 2 - p

y = 2 - \frac{1}{4}

Fasse zusammen

y = \frac{7}{4}
