inverse of (x^2+1)/(x^2+2)

inverse

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

\frac{1 - 2 x}{x - 1}, - \frac{1 - 2 x}{x - 1}

Solution steps

y = \frac{x ^{2} + 1}{x ^{2} + 2}

Replace

x

with

y

x = \frac{y ^{2} + 1}{y ^{2} + 2}

Solve for

y, x = \frac{y ^{2} + 1}{y ^{2} + 2}

\frac{1 - 2 x}{x - 1}, - \frac{1 - 2 x}{x - 1}

f (x) = 1 - 2 x + 4

\frac{x}{8 x - 3}

f (x) = \frac{3 - 2}{x - 5}

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