inverse of f(x)=x^2+x-6

inverse

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

\frac{- 1 + 4 x + 25}{2}, \frac{- 1 - 4 x + 25}{2}

Solution steps

y = x^{2} + x - 6

Replace

x

with

y

x = y^{2} + y - 6

Solve for

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

\frac{- 1 + 4 x + 25}{2}, \frac{- 1 - 4 x + 25}{2}

f (x) = \frac{5 x - 1}{3}

f (x) = \frac{x - 1}{1 + 4 x}

y = \frac{x + 1}{x}

f (x) = \frac{2}{3} x - 6

f (x) = \frac{1}{9} x - \frac{2}{9}
