inverse of ((1-sqrt(x)))/(1+sqrt(x))

inverse

\frac{( 1 - x )}{1 + x}

\frac{1 - 2 x + x ^{2}}{x ^{2} + 2 x + 1}

Solution steps

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

Replace

x

with

y

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

Solve for

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

\frac{1 - 2 x + x ^{2}}{x ^{2} + 2 x + 1}

f (x) = \frac{( x + 2 ) ^{2}}{1 + x}

y = 3 x^{\frac{2}{3}} - 2 x

f (x) = \frac{4}{x} + 8

f (x) = x^{\frac{1}{3}}
