leitkurve y=3x^2-12x+5

Lösung

leitkurve

y = 3 x^{2} - 12 x + 5

Lösung

y = - \frac{85}{12}

Schritte zur Lösung

Rewrite

y = 3 x^{2} - 12 x + 5

in the standard form

4 \cdot \frac{1}{12} (y - (- 7)) = (x - 2)^{2}

(h, k) = (2, - 7), p = \frac{1}{12}

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, - 7)

y-coordinate

y = - 7 - p

y = - 7 - \frac{1}{12}

Fasse zusammen

y = - \frac{85}{12}
