inverse of f(x)=2-x+sqrt(1-2x)

inverse

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

\frac{- 2 x + 2 + 8 x - 8}{2}, \frac{- 2 x + 2 - 8 x - 8}{2}

Solution steps

y = 2 - x + 1 - 2 x

Replace

x

with

y

x = 2 - y + 1 - 2 y

Solve for

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

\frac{- 2 x + 2 + 8 x - 8}{2}, \frac{- 2 x + 2 - 8 x - 8}{2}

3 (0.5 x - 2)^{2} - 2

f (x) = x^{2} - 2 x + 8

f (x) = 5 x^{2} - 3 x - 5

f (x) = (\frac{( 7 x )}{( 8 x - 1 )})

f (x) = 2 y - 5
