leitkurve 4x^2-6x-2

Lösung

leitkurve

4 x^{2} - 6 x - 2

Lösung

y = - \frac{69}{16}

Schritte zur Lösung

Rewrite

y = 4 x^{2} - 6 x - 2

in the standard form

4 \cdot \frac{1}{16} (y - (- \frac{17}{4})) = (x - \frac{3}{4})^{2}

(h, k) = (\frac{3}{4}, - \frac{17}{4}), p = \frac{1}{16}

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

(\frac{3}{4}, - \frac{17}{4})

y-coordinate

y = - \frac{17}{4} - p

y = - \frac{17}{4} - \frac{1}{16}

Fasse zusammen

y = - \frac{69}{16}
