inverse of (x-1)(x+2)

inverse

(x - 1) (x + 2)

\frac{- 1 + 4 x + 9}{2}, \frac{- 1 - 4 x + 9}{2}

Solution steps

y = (x - 1) (x + 2)

Replace

x

with

y

x = (y - 1) (y + 2)

Solve for

y, x = (y - 1) (y + 2)

\frac{- 1 + 4 x + 9}{2}, \frac{- 1 - 4 x + 9}{2}

f (x) = 9 - x^{2}

4 x + 3 y = - 3

f (x) = 2 x^{2} + 14 x - 25

f (x) = \frac{9 - 5 x}{9 + 2 x}

4 sin (x)
