leitkurve y= 1/4 x^2-5/2 x+13/4

Lösung

leitkurve

y = \frac{1}{4} x^{2} - \frac{5}{2} x + \frac{13}{4}

Lösung

y = - 4

Schritte zur Lösung

Rewrite

y = \frac{1}{4} x^{2} - \frac{5}{2} x + \frac{13}{4}

in the standard form

4 \cdot 1 \cdot (y - (- 3)) = (x - 5)^{2}

(h, k) = (5, - 3), 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

(5, - 3)

y-coordinate

y = - 3 - p

y = - 3 - 1

Fasse zusammen

y = - 4
