invers f(x)=-3x^2-6x+1

Lösung

invers

f (x) = - 3 x^{2} - 6 x + 1

- \frac{6 + - 12 x + 48}{6}, - \frac{6 - - 12 x + 48}{6}

Schritte zur Lösung

y = - 3 x^{2} - 6 x + 1

Ersetze

x

durch

y

x = - 3 y^{2} - 6 y + 1

Löse nach

y, x = - 3 y^{2} - 6 y + 1

- \frac{6 + - 12 x + 48}{6}, - \frac{6 - - 12 x + 48}{6}

in f l ec t i o n x^{3} - 3 x

in t erce pt s f (x) = 4 x - 12 y = 24

d o main p (x) = 2 x - 1

f (x) = x - 3

in v erse f (x) = 8 x - 6
