leitkurve y=-0.23x^2+1.87x+1.5

Lösung

leitkurve

y = - 0.23 x^{2} + 1.87 x + 1.5

Lösung

y = 6.38793 \dots

Schritte zur Lösung

Rewrite

y = - 0.23 x^{2} + 1.87 x + 1.5

in the standard form

4 (- 1.08695 \dots) (y - 5.30097 \dots) = (x - 4.06521 \dots)^{2}

(h, k) = (4.06521 \dots, 5.30097 \dots), p = - 1.08695 \dots

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

(4.06521 \dots, 5.30097 \dots)

y-coordinate

y = 5.30097 \dots - p

y = 5.30097 \dots - (- 1.08695 \dots)

Fasse zusammen

y = 6.38793 \dots
