leitkurve y=x^2+x+3

Lösung

leitkurve

y = x^{2} + x + 3

Lösung

y = \frac{5}{2}

Schritte zur Lösung

Rewrite

y = x^{2} + x + 3

in the standard form

4 \cdot \frac{1}{4} (y - \frac{11}{4}) = (x - (- \frac{1}{2}))^{2}

(h, k) = (- \frac{1}{2}, \frac{11}{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{1}{2}, \frac{11}{4})

y-coordinate

y = \frac{11}{4} - p

y = \frac{11}{4} - \frac{1}{4}

Fasse zusammen

y = \frac{5}{2}
