leitkurve y=(4x^3+11x^2+4x+21)/(x+3)

Lösung

leitkurve

y = \frac{4 x ^{3} + 11 x ^{2} + 4 x + 21}{x + 3}

Lösung

y = \frac{55}{8}

Schritte zur Lösung

Rewrite

y = \frac{4 x ^{3} + 11 x ^{2} + 4 x + 21}{x + 3}

in the standard form

4 \cdot \frac{1}{16} (y - \frac{111}{16}) = (x - \frac{1}{8})^{2}

(h, k) = (\frac{1}{8}, \frac{111}{16}), 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{1}{8}, \frac{111}{16})

y-coordinate

y = \frac{111}{16} - p

y = \frac{111}{16} - \frac{1}{16}

Fasse zusammen

y = \frac{55}{8}
