inverse of (x^2+1)/(x^2+3)

inverse

\frac{x ^{2} + 1}{x ^{2} + 3}

\frac{1 - 3 x}{x - 1}, - \frac{1 - 3 x}{x - 1}

Solution steps

y = \frac{x ^{2} + 1}{x ^{2} + 3}

Replace

x

with

y

x = \frac{y ^{2} + 1}{y ^{2} + 3}

Solve for

y, x = \frac{y ^{2} + 1}{y ^{2} + 3}

\frac{1 - 3 x}{x - 1}, - \frac{1 - 3 x}{x - 1}

f (x) = - x - 4 + 10

f (x) = \frac{3 x + 2}{2 + x}

f (x) = 0. 1^{x}

\frac{x + 3}{x ^{2} - 3}

f (x) = 3 (x + 5)^{2} - 4, x \leq - 5
