leitkurve y=4x^2-4x^1

Lösung

leitkurve

y = 4 x^{2} - 4 x^{1}

Lösung

y = - \frac{17}{16}

Schritte zur Lösung

Rewrite

y = 4 x^{2} - 4 x^{1}

in the standard form

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

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

y-coordinate

y = - 1 - p

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

Fasse zusammen

y = - \frac{17}{16}
