leitkurve y=(2x+5)^2

Lösung

leitkurve

y = (2 x + 5)^{2}

Lösung

y = - \frac{1}{16}

Schritte zur Lösung

Rewrite

y = (2 x + 5)^{2}

in the standard form:

4 \cdot \frac{1}{16} (y - 0) = (x - (- \frac{5}{2}))^{2}

(h, k) = (- \frac{5}{2}, 0), 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{5}{2}, 0)

y-coordinate

y = 0 - p

y = 0 - \frac{1}{16}

Fasse zusammen

y = - \frac{1}{16}
