foki y=(4x^3-7x^2-11x+5)/(4x+5)

Lösung

foki

y = \frac{4 x ^{3} - 7 x ^{2} - 11 x + 5}{4 x + 5}

Lösung

(\frac{3}{2}, - 1)

Schritte zur Lösung

Rewrite

y = \frac{4 x ^{3} - 7 x ^{2} - 11 x + 5}{4 x + 5}

in the standard form

4 \cdot \frac{1}{4} (y - (- \frac{5}{4})) = (x - \frac{3}{2})^{2}

(h, k) = (\frac{3}{2}, - \frac{5}{4}), p = \frac{1}{4}

Parabola is symmetric around the y-axis and so the focus lies a distance

p

from the center

(\frac{3}{2}, - \frac{5}{4})

along the y-axis

(\frac{3}{2}, - \frac{5}{4} + p)

= (\frac{3}{2}, - \frac{5}{4} + \frac{1}{4})
