foki-0.3x^2+2x+3

Lösung

foki

- 0.3 x^{2} + 2 x + 3

Lösung

(3.33333 \dots, 5.5)

Schritte zur Lösung

Rewrite

y = - 0.3 x^{2} + 2 x + 3

in the standard form

4 (- 0.83333 \dots) (y - 6.33333 \dots) = (x - 3.33333 \dots)^{2}

(h, k) = (3.33333 \dots, 6.33333 \dots), p = - 0.83333 \dots

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

p

from the center

(3.33333 \dots, 6.33333 \dots)

along the y-axis

(3.33333 \dots, 6.33333 \dots + p)

= (3.33333 \dots, 6.33333 \dots + (- 0.83333 \dots))
