leitkurve 2x^2-5x+5

Lösung

leitkurve

2 x^{2} - 5 x + 5

Lösung

y = \frac{7}{4}

Schritte zur Lösung

Rewrite

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

in the standard form

4 \cdot \frac{1}{8} (y - \frac{15}{8}) = (x - \frac{5}{4})^{2}

(h, k) = (\frac{5}{4}, \frac{15}{8}), p = \frac{1}{8}

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}{4}, \frac{15}{8})

y-coordinate

y = \frac{15}{8} - p

y = \frac{15}{8} - \frac{1}{8}

Fasse zusammen

y = \frac{7}{4}
