leitkurve y=12x^2-72x+77

Lösung

leitkurve

y = 12 x^{2} - 72 x + 77

Lösung

y = - \frac{1489}{48}

Schritte zur Lösung

Rewrite

y = 12 x^{2} - 72 x + 77

in the standard form

4 \cdot \frac{1}{48} (y - (- 31)) = (x - 3)^{2}

(h, k) = (3, - 31), p = \frac{1}{48}

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

(3, - 31)

y-coordinate

y = - 31 - p

y = - 31 - \frac{1}{48}

Fasse zusammen

y = - \frac{1489}{48}
