leitkurve 7x^2-5x+9

Lösung

leitkurve

7 x^{2} - 5 x + 9

Lösung

y = \frac{113}{14}

Schritte zur Lösung

Rewrite

y = 7 x^{2} - 5 x + 9

in the standard form

4 \cdot \frac{1}{28} (y - \frac{227}{28}) = (x - \frac{5}{14})^{2}

(h, k) = (\frac{5}{14}, \frac{227}{28}), p = \frac{1}{28}

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}{14}, \frac{227}{28})

y-coordinate

y = \frac{227}{28} - p

y = \frac{227}{28} - \frac{1}{28}

Fasse zusammen

y = \frac{113}{14}
