leitkurve y=x^2-4x+3

Lösung

leitkurve

y = x^{2} - 4 x + 3

Lösung

y = - \frac{5}{4}

Schritte zur Lösung

Rewrite

y = x^{2} - 4 x + 3

in the standard form

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

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

(2, - 1)

y-coordinate

y = - 1 - p

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

Fasse zusammen

y = - \frac{5}{4}
