leitkurve 5x-x^2

Lösung

leitkurve

5 x - x^{2}

Lösung

y = \frac{13}{2}

Schritte zur Lösung

Rewrite

y = 5 x - x^{2}

in the standard form

4 (- \frac{1}{4}) (y - \frac{25}{4}) = (x - \frac{5}{2})^{2}

(h, k) = (\frac{5}{2}, \frac{25}{4}), p = - \frac{1}{4}

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}, \frac{25}{4})

y-coordinate

y = \frac{25}{4} - p

y = \frac{25}{4} - (- \frac{1}{4})

Fasse zusammen

y = \frac{13}{2}
